WebFukuyama and co-workers reported a palladium-catalyzed cross-coupling between thioesters and organozinc reagents to afford the corresponding ketone products. The reaction proceeds under mild conditions, shows good functional group tolerance, and affords access to the product in excellent yields. WebOct 17, 2024 · Suzuki-Miyaura cross-couplings of amides offer an approach to the synthesis of ketones that avoids the use of basic or pyrophoric nucleophiles. However, these reactions require glovebox manipulations, thus limiting their practicality. We report a benchtop protocol for Suzuki-Miyaura cross-couplings of aliphatic amides that utilizes a … In organic chemistry, a cross-coupling reaction is a reaction where two different fragments are joined. Cross-couplings are a subset of the more general coupling reactions. Often cross-coupling reactions require metal catalysts. One important reaction type is this: R−M + R'−X → R−R' + MX (R, R' = organic fragments, usually aryle; M = main group center such as Li or MgX; X = halide) cam mccormick degree
