Abstract

Abstract An imidazolium chloride tagged palladium (II) complex has been conveniently prepared and structurally analyzed. It is active toward cross-coupling of arylboronic acid with aryl halide and benzoyl chloride, giving moderate to high yield of the desired biaryls and aryl ketones, respectively. The present phosphine-free (N–N) Pd (II) complex could be efficiently recycled at least four times with minor decrease of activity in the aqueous Suzuki–Miyaura ...
