2-Aminophenyl diphenylphosphinite as a new ligand for heterogeneous palladium-catalyzed Heck-Mizoroki reactions in water in the absence of any organic co-solvent

In this article, 2-aminophenyl diphenylphosphinite has been introduced as a new ligand for the Heck-Mizoroki reactions of aryl halides with styrene and n-butylacrylate in water in the presence of palladium acetate. This ligand is easily prepared from the reaction of chlorodiphenyl phosphine with 2-aminophenol in high yield. Pre-catalyst [Pd(OAc)2] in the presence of the ligand produces a black solid mass. The solid catalyst has been recycled for the reaction of bromobenzene with styrene for six runs without appreciable loss of its catalytic activity.
