Abstract

Abstract The Suzuki–Miyaura cross-coupling of aryl sulfamates and boronic acids was investigated by using [1, 3-bis (diphenylphosphanyl) propane] nickel (II) chloride {NiCl 2 (dppp)} as the catalyst. The results showed that NiCl 2 (dppp) is a highly active and general catalyst that allows effective Suzuki–Miyaura cross-coupling of aryl sulfamates with a slight excess amount of the boronic acid (1.2 equiv.) in the presence of a low catalyst loading ( ...
