摘要

The palladium-catalyzed direct arylation of aromatic compounds with aryl halides has been proposed to involve an arylpalladium carboxylate intermediate. However, isolated arylpalladium complexes, which undergo C–H bond cleavage of aromatic substrates without the aid of additional activators or promoters, have been scarcely documented. This paper reports that [PdAr (μ-O2CR)(PPh3)] n complexes (1: Ar= Ph, 2-MeC6H4, 2, 6-Me2C6H3; R ...
