Summary: The nickel-catalyzed intermolecular Heck reaction of cycloalkenes with aryl triflates, mesylates, and tosylates shows excellent enantiomeric ratios. Additionally, the asymmetric reductive Heck reaction is also applicable to a 2-cyclopentenone ketal, equivalent to conjugate arylation of the enone itself.

Summary: Direct N-arylation of sulfonamides using a combination of copper and oxalamides (or 4-hydroxypicolinamides) as catalysts is an efficient method. It allows for a wide range of reactions between sulfonamides and (hetero)aryl bromides, and even works well with primary sulfonamides and (hetero)aryl chlorides under the catalysis of Cu2O and a 4-hydroxypicolinamide.

Summary: This article describes the development of excited-state palladium-catalyzed alkylative cyclization of acrylamides and the alkylation of quinoxalinones. The highlights of this reactivity manifold include the use of various unactivated alkyl halides as alkyl radical precursors and a simple catalyst system. The reactions have a wide scope, occur under mild conditions, and provide excellent yields of products.

Summary: A nickel catalysis system has been developed for the desulfonylative C(sp(2))-C(sp(2)) reductive cross-coupling reactions of aryl sulfone derivatives with aryl bromides to form diverse biaryl compounds. The isolated and confirmed Ar-Ni(II)-SO(2)CF3 complex with a phosphine ligand through oxidative addition of aryl sulfone to Ni(0) species provides solid evidence for understanding the C(Ar)-SO2 bond activation and reaction mechanism.

Summary: The first Pd(0)-catalyzed synthesis of aryl-methylene ethers from hydrobenzoxazoles (hydrothiazoles) using dichloromethane (DCM) as the C1 feedstock is reported. This protocol demonstrates a broad substrate scope (38 examples) and wide tolerance to functional groups. The aryl-methylene ether adducts have been successfully coupled with isocyanate to provide bis-iminoisoindolinones. In this reaction, DCM serves as a twofold electrophile, undergoing double C-Cl bond cleavage to react with hydrobenzoxazoles.

Summary: A nickel-catalyzed direct cross-coupling between unactivated aryl fluorides and aryl bromides was achieved. This one-pot reaction proceeds effectively at room temperature in THF, avoiding the use of preformed and sensitive organometallic reagents. The desired biaryls are produced in modest to good yields via C-F bond cleavage in the presence of a phosphine ligand and magnesium powder (with or without TMSCl).

Summary: This article introduces a Suzuki-Miyaura cross-coupling reaction of alpha-chloroacetates or alpha-chloroacetamides with arylboronic acids under visible-light irradiation, providing a mild method for the synthesis of alpha-arylacetates and alpha-arylacetamides. Additionally, the authors successfully synthesized a key intermediate of the plant hormone auxin, indole-3-acetic acid derivative, from 1-Boc-indole in two steps by combining an iridium-catalyzed C-H borylation and a palladium-catalyzed cross-coupling reaction.

Summary: An improved carbonylation method for amide bond formation between aryl iodides and aromatic amines is presented, which does not require a phosphine ligand unlike conventional Pd catalysis. The catalyst system consists of bis(dibenzylideneacetone)palladium (0.5 mol %) and DBU (10 mol %). This method allows the synthesis of various aromatic amides and can be scaled to gram order synthesis under low carbon monoxide pressure.

Summary: A chemoselective Pd-mediated carbonylative Negishi-type catalytic protocol for the synthesis of (hetero)-aryl ketones is described. The protocol utilizes the PEPPSI-IPr precatalyst and CO gas at atmospheric pressure to facilitate the carbonylative coupling between various C-(sp3)-hybridized organozinc reagents and a wide range of aryl iodides, including substrates with aldehyde, aniline, phenol, or carboxylic acid groups, and heteroaryls.

Summary: Photoinduced enhancement of hydricity of palladium hydride species enables unprecedented hydride addition-like (hydridic) hydropalladation of electron-deficient alkenes, which allows for chemoselective head-to-tail cross-hydroalkenylation of electron-deficient and electron-rich alkenes. This mild and general protocol works with a wide range of densely functionalized and complex alkenes. Notably, this approach also allows for highly challenging cross-dimerization of electronically diverse vinyl arenes and heteroarenes.

Summary: In this study, the Pd-catalyzed cross-coupling reaction between α-pinene derivative - pinacarvone O-methyl oxime and aryl halides was described. Surprisingly, the formation of the C-C coupling product was accompanied by an unexpected opening of the pinene bicyclic structure. The reaction conditions were carefully optimized and the reaction mechanism was proposed based on structural and computational data analysis.
