Abstract
Copper-catalyzed regioselective aminothiolation of terminal and internal alkenes with N-fluorobenzenesulfonimide and thiols has been developed. The three-component reaction is promoted by the addition of dimethyl sulfide. In addition to aromatic alkenes, aliphatic alkenes are subjected to the reaction, affording various aminothiolation adducts as single regioisomers. The radical process is proposed by preliminary mechanistic studies, involving radical trap and radical clock experiments.

Abstract
Two-component Giese type radical additions are highly practical and established reactions. Herein, three-component radical conjugate additions of unactivated alkenes to Michael acceptors are reported. Amidyl radicals, oxidatively generated from α-amido oxy acids using redox catalysis, act as the third reaction component which add to the unactivated alkenes. The adduct radicals engage in Giese type additions to Michael acceptors to provide, after reduction, the three-component products in an overall alkene carboamination reaction. Transformations which can be conducted under practical mild conditions feature high functional group tolerance and broad substrate scope.

Abstract
Radical-radical couplings are mostly nearly diffusion-controlled processes. Therefore, the selective cross-coupling of two different radicals is challenging and not a synthetically valuable transformation. However, if the radicals have different lifetimes and if they are generated at equal rates, cross-coupling will become the dominant process. This high cross-selectivity is based on a kinetic phenomenon called the persistent radical effect (PRE). In this Review, an explanation of the PRE supported by simulations of simple model systems is provided. Radical stabilities are discussed within the context of their lifetimes, and various examples of PRE-mediated radical-radical couplings in synthesis are summarized. It is shown that the PRE is not restricted to the coupling of a persistent with a transient radical. If one coupling partner is longer-lived than the other transient radical, the PRE operates and high cross-selectivity is achieved. This important point expands the scope of PRE-mediated radical chemistry. The Review is divided into two parts, namely 1) the coupling of persistent or longer-lived organic radicals and 2) "radical-metal crossover reactions"; here, metal-centered radical species and more generally longer-lived transition-metal complexes that are able to react with radicals are discussed-a field that has flourished recently.

Abstract
The development of intermolecular alkene aminopyridylation has great potential for quickly increasing molecular complexity with two valuable groups. Here we report a strategy for the photocatalytic aminopyridylation of alkenes using a variety of N-aminopyridinium salts as both aminating and pyridylating reagents. Using Eosin Y as a photocatalyst, amino and pyridyl groups are simultaneously incorporated into alkenes, affording synthetically useful aminoethyl pyridine derivatives under mild reaction conditions. Remarkably, the C4-regioselectivity in radical trapping with N-aminopyridinium salt can be controlled by electrostatic interaction between the pyridinium nitrogen and sulfonyl group of β-amino radical. This transformation is characterized by a broad substrate scope, good functional group compatibility, and the utility of this transformation was further demonstrated by late-stage functionalization of complex biorelevant molecules. Combining experiments and DFT calculations on the mechanism of the reaction is investigated to propose a complete mechanism and regioselectivity.

Abstract
A protocol for the three-component 1,4-carboamination of dienes is described. Synthetically versatile Weinreb amides were coupled with 1,3-dienes and readily available dioxazolones as the nitrogen source using [Cp*RhCl2 ]2 -catalyzed C-H activation to deliver the 1,4-carboaminated products. This transformation proceeds under mild reaction conditions and affords the products with high levels of regio- and E-selectivity. Mechanistic investigations suggest an intermediate RhIII -allyl species is trapped by an electrophilic amidation reagent in a redox-neutral fashion.

Abstract
A phosphite-mediated [2,3]-aza-Wittig rearrangement has been developed for the regio- and enantioselective allylic alkylation of six-membered heteroaromatic compounds (azaarenes). The nucleophilic phosphite adducts of N-allyl salts undergo a stereoselective base-mediated aza-Wittig rearrangement and dissociation of the chiral phosphite for overall C-H functionalization of azaarenes. This method provides efficient access to tertiary and quaternary chiral centers in isoquinoline, quinoline, and pyridine systems, tolerating a broad variety of substituents on both the allyl part and azaarenes. Catalysis with chiral phosphites is also demonstrated with synthetically useful yields and enantioselectivities.

Abstract
The reaction of readily available and bench-stable N-alkoxypyridinium salts with arylboronic and vinylboronic acids afforded δ-aryl and δ-vinyl alcohols, respectively, in the presence of fac-Ir(ppy)3 and Cu(OTf)2 dual catalysts. The reaction takes place through a domino process involving the reductive generation of alkoxyl radicals, 1,5-hydrogen atom transfer (1,5-HAT) and the copper-catalyzed cross-coupling reaction of the resulting translocated carbon radicals with boronic acids. Complementary to the Minisci reaction, this method allows for the arylation of nucleophilic alkyl radicals with both electron-rich and electron-poor arenes under mild reaction conditions.

Abstract
A tandem radical relay strategy was realized for the first Cu(I)-catalyzed enantioselective phosphinocyanation of styrenes. In this reaction, tBuOOSiMe3 generated in situ from tBuOOH serves as a radical initiator to trigger t-butoxy radical production upon oxidization of L*Cu(I) species via proton-coupled-electron transfer (PCET) pathway, which leads to sequential phosphinoyl radical and benzyl radical formations. The resultant β-cyanodiarylphosphine oxides could be easily converted to a series of chiral γ-amino phosphine ligands.

Abstract
A novel nickel-catalyzed 1,2-arylboration of vinylarenes is reported. A variety of 2-boryl-1,1-diarylalkanes, which constitute a class of significant pharmacophores, are efficiently prepared from readily available olefins and aryl halides in the presence of bis(pinacolato)diboron under mild reaction conditions. The success of this three-component cascade is mainly attributed to the redox-active nitrogen-based ligand. Moreover, this method exhibits good functional group tolerance and excellent chemo- and stereoselectivity.

Abstract
Classical 1,4-dicarbofunctionalization of 1,3-enynes employs organometallic reagents as nucleophiles to initiate the reaction. We report a copper-catalyzed 1,4-alkylarylation of 1,3-enynes with alkyl diacyl peroxides as masked alkyl electrophiles and aryl boronic acids as nucleophiles, selectively affording structurally diversified tetrasubstituted allenes under mild conditions. Mechanistic studies suggest that an allenyl radical might be involved.

Abstract
A transition-metal-free radical 1,2-amidoalkynylation of unactivated alkenes is presented. α-Amido-oxy acids were used as amidyl radical precursors, which were oxidized by an organic photoredox catalyst (4CzlPN). The electrophilic N-radicals chemoselectively reacted with various aliphatic alkenes and the adduct radicals were then trapped by ethynylbenziodoxolone (EBX) reagents to eventually provide the amidoalkynylation products. These transformations, which were conducted under practical and mild conditions, showed high functional group tolerance and broad substrate scope. Mechanistic studies supported the radical nature of these cascades.

Abstract
Alkene aminoarylation with a single, bifunctional reagent is a concise synthetic strategy. We report a catalytic protocol for the addition of arylsulfonylacetamides across electron-rich alkenes with complete anti-Markovnikov regioselectivity and excellent diastereoselectivity to provide 2,2-diarylethylamines. In this process, single-electron alkene oxidation enables carbon-nitrogen bond formation to provide a key benzylic radical poised for a Smiles-Truce 1,5-aryl shift. This reaction is redox-neutral, exhibits broad functional group compatibility, and occurs at room temperature with loss of sulfur dioxide. As this process is driven by visible light, uses readily available starting materials, and demonstrates convergent synthesis, it is well suited for use in a variety of synthetic endeavors.

Abstract
The direct transformation of C-H bonds into diverse functional groups represents one of the most atom- and step-economical strategies for organic synthesis and has received substantial attention over the last few decades. Despite recent advances, asymmetric C-H bond functionalizations are less developed, especially asymmetric oxidations of sp3 C-H bonds. Inspired by enzyme (e.g., P450) catalysis, chemists have made great efforts to develop non-enzymatic systems for enantioselective oxidations of sp3 C-H bonds. However, the involvement of highly reactive radical intermediates makes enantioselective transformations extremely challenging. In this Account, we present our recent studies on the enantioselective induction of prochiral benzylic radicals using a chiral bisoxazoline (Box)/Cu catalytic system. This reaction system was developed on the basis of our extensive studies of copper-catalyzed intermolecular alkene difunctionalizations, such as azidotrifluoromethylations, trifluoromethylcyanations, and trifluoromethylarylations. In these reactions, the proposed catalytic cycle starts from the oxidation of the Cu(I) species by the activated Togni-I reagent (via a Lewis acid/base interaction with a silyl reagent or arylboronic acid) through a single electron transfer process. The generated CF3 radical can efficiently add to the alkene, and the resultant carbon-centered radical is subsequently trapped by an active Cu(II) species bearing a nucleophile (e.g., an N3, CN, or Ar moiety) to form a new C-heteroatom or C-C bond and regenerate the Cu(I) catalyst. Kinetic studies of the trifluoromethylarylation of alkenes support a Cu(I/II/III) catalytic cycle in which the carbon radical reacts with the Cu(II) species to form a highly reactive Cu(III) intermediate and its reductive elimination contributes to the final bond formation. This assumption inspired us to explore asymmetric radical transformations by introducing chiral ligands. Enantioselective cyanations and arylations of benzylic radicals have been demonstrated in the presence of chiral Box/Cu(I) catalysts, and a series of asymmetric difunctionalizations of styrenes have been successfully achieved. In addition, by means of the same benzylic radical trapping process, enantioselective decarboxylative cyanations have been demonstrated using a cooperative photocatalysis and copper catalysis system. Compared with radical addition and decarboxylative processes, hydrogen atom abstraction (HAA) provides direct and facile access to benzylic radicals. By using bisbenzenesulfonimidyl radical for HAA, our group has developed an enantioselective cyanation of benzylic C-H bonds via a copper-catalyzed radical relay, and excellent reactivity and enantioselectivity were achieved in the presence of chiral Box/Cu(I) catalysts. In addition, a regioselective benzylic C-H bond arylation proceeding through a similar process was also developed, providing simple access to 1,1-diarylalkanes. Notably, alkyl arenes were used as the limiting reagent in these reactions, which allowed the late-stage functionalization of sp3 C-H bonds in complex molecules, including natural products, pharmaceuticals, and agrochemicals.
