Palladium(II)-Catalyzed Conjugate Phosphination of Electron-Deficient Acceptors
摘要:
A general protocol for the conjugate transfer of diphenyl-, dicyclohexyl-, and di-tert-butylphosphinyl groups from silylphosphlnes to cyclic and acyclic electron-deficient acceptors employing a bench-stable palladium(II) catalyst Is reported. Several E and Z configured alpha,beta-unsaturated carbonyl and carboxyl acceptors (including imides) as well as nitroalkenes participate in this palladium(II)-catalyzed process in high chemical yields.
