Abstract
We have demonstrated a Pd(0)-catalyzed Heck/C(sp3)-H activation cascade for the synthesis of spirocyclopropyl oxindoles in high yields from easily accessible ortho-bromoacrylamides. The formation of spirocyclopropyl oxindole is guided by an unconventional four-membered palladacycle through C(sp3)-H activation. The reaction exhibits a wide range of substrate scope and operates efficiently with a mere 0.5 mol % of Pd-catalyst. In addition, the use of microwave conditions facilitates rapid completion of the reaction. Furthermore, this spirocyclopropanation strategy can be coupled with [3 + 2] cycloaddition to produce spiropyrrolidine oxindoles, offering a valuable approach for the preparation of alkaloids such as (±)-horsfiline and (±)-coerulescine.

Abstract
Solvent-switchable and site-selective phosphorylation of imidazoles at the C2 or C5 position of the imidazole ring was achieved via 1,4-palladium migration. P-Chiral tert-butyl(aryl)phosphine oxides were cross-coupled to 1-(2-bromophenyl)-1H-imidazoles with high enantiospecificity, thereby leading to a novel class of chiral imidazole-based phosphine oxides. As proof of concept, reduction of an analogue yielded the corresponding P-chiral 2-phosphinyl imidazole ligand, which was shown to induce high enantioselectivity in the formation of axially chiral molecules synthesized via Pd-catalyzed Suzuki-Miyaura cross-coupling.

Abstract
Efficient palladium-catalyzed vinylic C-H alkenylation and allenylation of gem-disubstituted ethylenes with N-tosylhydrazones of aryl alkyl and diaryl ketones were achieved to access trisubstituted 1,3-dienes and tetrasubstituted allenes, respectively. An aryl to vinyl 1,4-palladium migration/carbene insertion/β-hydride elimination sequence proceeded to switch the chemo- and regioselectivities to give structurally diverse products. Use of 2-FC6H4OH additive enables enhancement of the reaction efficiency through accelerating the key 1,4-palladium migration process.

Abstract
A palladium-catalyzed remote C-H silylation reaction has been developed through vinylic to aryl 1,4-palladium migration. By using alkyne-tethered aryl iodides as the starting materials and hexamethyldisilane as the silylating reagent, the reaction involves cascade intramolecular carbopalladation, 1,4-palladium migration, and silylation with hexamethyldisilane, and leads to the formation of exocyclic alkene-containing 5-silylisoquinolines as the final products.

Abstract
A Pd-catalyzed synthesis of 3,4,5-trisubstituted cyclopentenes from diazabicyclic olefins and o-iodobenzoates has been developed. The hitherto unknown cascade process involves three stages: carbopalladation, oxypalladation and a Tsuji-Trost reaction. We have also developed a facile route involving a novel benzylic C-H activation towards cyclopentenoindane moieties.

Abstract
The Diels-Alder reaction between 2-methylfuran and 3-bromobenzyne (3), which was generated under mild conditions from 1,3-dibromobenzene and lithium diisopropylamide (LDA), gives a mixture of regioisomeric 1,4-dihydro-1,4-epoxynaphthalenes 4 and 5. A subsequent two-step deoxygenation affords the corresponding 1-bromo-8-methylnaphthalene (1) and 1-bromo-5-methylnaphthalene (2) in high yields.

Abstract
Through-space metal/hydrogen shift is an important strategy for transition-metal-catalyzed C-H bond activation. Here we describe the synthesis and characterization of a Rh(I) 2,6-dimethoxybenzoate complex that underwent stoichiometric rearrangement via a highly unusual 1,3-rhodium migration. This aryl-to-aryl 1,3-Rh/H shift was also demonstrated in a Rh(I)-catalyzed decarboxylative conjugate addition to form a C-C bond at a meta position instead of the ipso-carboxyl position. A deuterium-labeling study under the conditions of Rh(I)-catalyzed protodecarboxylation revealed the involvement of an ortho-methoxy group in a multistep pathway of consecutive sp(3) and sp(2) C-H bond activations.

Abstract
A new protocol for titrating nonstabilized diazoalkane solutions by quantitative (19)F NMR is reported. An excess of 2-fluorobenzoic acid dissolved in CDCl(3) is treated with the diazoalkane solution at a low temperature, immediately forming the corresponding 2-fluorobenzoate ester upon warming. A significant difference in the (19)F chemical shift between the ester and acid is seen, allowing facile and accurate integration to determine titer. The procedure is safe, rapid, and indicates the active diazoalkane concentration with high precision.

Abstract
The catalytic activation of a C-H bond is a fundamentally important organic transformation. There are now numerous reports of palladium-mediated C-H activation by the through-space interaction of a palladium center with a neighboring C-H bond. This type of C-H activation can lead to a net "palladium migration" from the carbon atom where the palladium is first introduced to a remote carbon atom where C-H activation occurs. This process provides a novel method to introduce a palladium moiety into a position where direct palladium introduction may not be straightforward. This process is accompanied by concurrent migration of a hydrogen atom in the direction opposite to that of the palladium migration. Analogous rhodium migrations have also been reported. In this account, different types of palladium and rhodium migrations are reviewed and the reaction mechanism is discussed.

Abstract
An efficient catalytic system has been developed for the synthesis of benzocyclobutenes by C-H activation of methyl groups. The optimal conditions employed a combination of Pd(OAc) 2 and P ( t )Bu 3 as catalyst, K 2CO 3 as the base, and DMF as solvent. A variety of substituted BCB were obtained under these conditions with yields in the 44-92% range, including molecules that are hardly accessible by other methods. The reaction was found limited to substrates bearing a quaternary benzylic carbon, but benzocyclobutenes bearing a tertiary benzylic carbon could be obtained indirectly from diesters by decarboxylation. Reaction substrates bearing a small substituent para to bromine gave an unexpected regioisomer that likely arose from a 1,4-palladium migration process. The formation of this "abnormal" regioisomer could be suppressed by introducing a larger subsituent para to bromine. DFT(B3PW91) calculations on the reaction of 2-bromo-tert-butylbenzene with Pd(P ( t )Bu 3) with different bases (acetate, bicarbonate, carbonate) showed the critical influence of the coordination mode of the base to induce both an easy C-H activation and to allow for a pathway for 1,4-palladium migration. Carbonate is shown to be more efficient than the two other bases because it can abstract the proton easily and at the same time maintain kappa (1)-coordination without extensive electronic reorganization.
