Cross-couplings between benzylic and aryl halides "on water": synthesis of diarylmethanes.


PMID 20062862

Abstract

A remarkably simple entry to unsymmetrical diarylmethanes has been developed that relies on an in situ organozinc-mediated, palladium-catalyzed cross-coupling. Thus, by mixing a benzyl and aryl halide together in the presence of Zn metal and a Pd catalyst, diarylmethanes are formed at room temperature without assistance by a surfactant; hence, "on water".
