Abstract

We report a novel method for the preparation of PBP-pincer complexes from bis(phosphine)boronium salts. The central (R3P)2HB-moiety in a palladium complex is demonstrated to be a L-type ligand, therewith completing a series of pincer-type complexes with Z-, X- and L-type boron-based ligands, respectively.
