Buchwald-Hartwig amination using Pd(i) dimer precatalysts supported by biaryl phosphine ligands.
DALTON TRANSACTIONS(2018)
摘要
We report the synthesis of air-stable Pd(i) dimer complexes featuring biaryl phosphine ligands. Catalytic experiments suggest that these complexes are competent precatalysts that can mediate cross-coupling amination reactions between aryl halides with both aliphatic and aromatic amine nucleophiles. This work represents an expansion of the air-stable precatalyst toolbox for Pd-catalyzed cross-coupling transformations.
