Abstract
A transition-metal-free hydrosilylation of allenes is reported herein by using commercially available lithium triethylborohydride (LiHBEt3) as the catalyst. Both mono- and disubstituted allenes could be hydrosilylated with primary or secondary silanes effectively. This reaction represents an environmental and economic method to prepare (E)-allylsilanes in good yields along with decent selectivities.

Abstract
A copper-catalyzed regiodivergent hydrosilylation of a wide range of simple allenes is reported. Linear and branched allylsilanes were formed by judicious choice of solvents. Furthermore, branched allylsilanes were obtained with high enantioselectivity (up to 97% enantiomeric excess) with the aid of a C2-symmetric bisphosphine ligand in the unprecedented asymmetric allene hydrosilylation.

Abstract
Hydroboration of 1,3-dienes can provide useful intermediates with multiple functionalities. However, achieving high regioselectivity is still a challenge. Recent experimental research studies indicate that this challenge could be overcome by the ligand effect. We made DFT calculations to elucidate the origin of ligand controlled regioselectivity in cobalt catalyzed hydroboration of 2-substituted 1,3-diene. The following conclusions have been reached: when using PHOX ((2-oxazolinyl)-phenyldiphenylphosphine) as the ligand, the favorable 1,4-selective oxidative hydrogen migration pathway was suggested to start with the rate-determining step of 1,4-selective oxidative hydrogen migration followed by reductive boryl migration. The unique 1,4-selectivity is proposed to be a result of the less steric hindrance between the substrate and the ligand PHOX. When dppp (1,3-bis-(diphenylphosphino)propane) is used as the ligand, the favorable pathway is proposed to be a 1,2-selective oxidative boryl migration pathway which involves 1,2-selective oxidative boryl migration and reductive hydrogen migration. Interestingly, another smaller-bite angle bisphosphine ligand dppe (1,2-bis(diphenylphosphino)ethane) favors the 1,4-selective oxidative boryl migration pathway. DFT calculations revealed that the preferred oxidative boryl migration pathway with both dppp and dppe is attributed to their electron-rich properties which accelerate the oxidative boryl migration step. The larger bite angle of dppp than that of dppe leads to bulkier steric hindrance and promotes 1,2-selective reductive hydrogen migration. On the other hand, for dppe with a smaller bite angle, the steric effect in the reductive hydrogen migration step is not dominant and 1,4-selective reductive hydrogen migration is favored. It is expected that the analysis of the ligand effect on the regioselectivity would enable further catalyst design.

Abstract
Density functional theory (DFT) calculations have been performed to study the Pd-catalyzed C-H functionalization of (E)-N-methoxy cinnamamide (E1), which selectively provides the α-C-H activation products (EP as minor product and its C═C rotation isomer ZP' as major product). Three crucial issues are solved: (i) The detailed mechanism leading to ZP' is one issue. The computational analyses of the mechanisms proposed in previously experimental and theoretical literature do not seem to be consistent with the experimental findings due to the high barriers involved. Alternatively, we present a novel oxidation/reduction-promoted mechanism featuring the Pd(0) → Pd(II) → Pd(0) transformation. The newly proposed mechanism involves the initial coordination of the active catalyst PdL2 (L = t-BuCN) with the C═C bond in EP, followed by the oxidative cyclization/reductive decyclization-assisted C═C double-bond rotation processes resulting in ZP' and regeneration of PdL2. (ii) The origin of the product E/Z selectivity is the second issue. On the basis of the calculated results, it is found that, at the initial stage of the reaction, EP is certainly completely generated, while no ZP' formation occurred. Once E1 is used up, EP immediately acts as the partner of the new catalytic cycle and sluggishly evolves into ZP'. A small amount of generated ZP' would reversibly transform to EP due to the higher barrier involved. (iii) The intrinsic reasons for the regioselectivity are the third issue. The calculated results indicate that the regioselectivity for α-C-H activation is mainly attributed to the stronger electrostatic attraction between the α-C and the metal center.

Abstract
The catalytic cycles of palladium-catalyzed silylation of aryl iodides, which are initiated by oxidative addition of hydrosilane or aryl iodide through three different mechanisms characterized by intermediates R3 Si-PdII -H (Cycle A), Ar-PdII -I (Cycle B), and PdIV (Cycle C), have been explored in detail by hybrid DFT. Calculations suggest that the chemical selectivity and reactivity of the reaction depend on the ligation state of the catalyst and specific reaction conditions, including feeding order of substrates and the presence of base. For less bulky biligated catalyst, Cycle C is energetically favored over Cycle A, through which the silylation process is slightly favored over the reduction process. Interestingly, for bulky monoligated catalyst, Cycle B is energetically more favored over generally accepted Cycle A, in which the silylation channel is slightly disfavored in comparison to that of the reduction channel. Moreover, the inclusion of base in this channel allows the silylated product become dominant. These findings offer a good explanation for the complex experimental observations. Designing a reaction process that allows the oxidative addition of palladium(0) complex to aryl iodide to occur prior to that with hydrosilane is thus suggested to improve the reactivity and chemoselectivity for the silylated product by encouraging the catalytic cycle to proceed through Cycles B (monoligated Pd0 catalyst) or C (biligated Pd0 catalyst), instead of Cycle A.

Abstract
In this account, our studies on nickel-catalyzed hydrosilylation reactions are described. A series of (salicylaldiminato)methylnickel complexes efficiently catalyze alkene hydrosilylation under ambient reaction conditions. Commercially available Ni(II) salts, Ni(acac)2 (acac = acetylacetonato) and its derivatives bis(hexafluoroacetylacetonato)nickel(II) and bis (2,2,6,6-tetramethyl-3,5-heptanedionato)nickel(II), also act as versatile hydrosilylation catalyst precursors in the presence of NaBHEt3 . These systems catalyze the hydrosilylation of various alkenes such as industrially important siloxy-, amino-, and epoxy-substituted ones. The arene-supported cationic nickel allyl complexes also serve as good catalysts for alkene hydrosilylation at room temperature. These nickel complexes exhibit high selectivity towards the reaction using secondary hydrosilanes. Mechanistic studies based on experiments and DFT calculations support a novel mechanism, which includes a facile Si-H bond cleavage and a Si-C bond formation, assisted by the cooperative action of the allyl ligand.

Abstract
Lewis base N-heterocyclic carbene (NHC)-catalyzed annulation is the subject of extensive interest in synthetic chemistry, but the reaction mechanisms, especially the unexpected chemoselectivity of some of these reactions, are poorly understood. In this work, a systematic theoretical calculation has been performed on NHC-catalyzed annulation between allenals and chalcone. Multiple possible reaction pathways (A-E) leading to three different products have been characterized. The calculated results reveal that NHC is more likely to initiate the reaction by nucleophilic attack on the center carbon atom of the allene group but not the carbonyl carbon atom in allenals leading to the Breslow intermediate, which is remarkably different from the other NHC-catalyzed annulations of unsaturated aldehydes with chalcones. The computed energy profiles demonstrate that the most energetically favorable pathway (A) results in polysubstituted pyranyl aldehydes, which reasonably explains the observed chemoselectivity in the experiment. The observed chemoselectivity is demonstrated to be thermodynamically but not kinetically controlled, and the stability of the Breslow intermediate is the key for the possibility of homoenolate pathway D and enolate pathway E. This work can improve our understanding of the multiple competing pathways for NHC-catalyzed annulation reactions of unsaturated aldehydes with chalcones and provide valuable insights for predicting the chemoselectivity for this kind of reaction.

Abstract
![]()
Advances
in hydroarylation have been achieved by the development
of a one-pot regioselective allene hydrosilylation/Pd(0)-catalyzed
cross-coupling protocol. The regioselectivity is primarily governed
by N-heterocyclic carbene (NHC) ligand identity in
the hydrosilylation step and is preserved in the subsequent cross-coupling
reaction. This methodology affords streamlined access to functionalized
1,1-disubstituted alkenes with excellent regiocontrol.
