Abstract

A new class of easily accessible hemilabile benzimidazolyl phosphine ligands has been developed. The ligand skeleton is prepared from commercially available and inexpensive o- phenylenediamine and 2-bromobenzoic acid. With catalyst loading down to 0.5 mol% palladium, excellent catalytic activity towards the Suzuki–Miyaura coupling of aryl mesylates is still observed. This represents the lowest catalyst loading achieved so far for this ...
