General description

Ethyl 4-bromobenzoate is an ester having electron-withdrawing substituent. It undergoes reduction with potassium diisobutyl-t-butoxyaluminum hydride (PDBBA) at 0°C to yield aldehydes. Reaction of ethyl 4-bromobenzoate and substituted benzyl chloride with zinc dust and a Pd catalyst is reported.

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
