Abstract

A new family of dihydrobenzoazaphosphosphole ligands was prepared and shown to enable modification of the phosphine electronic character by variation of the N-substituent. This new family of phosphines was shown to be highly active in the Pd-catalyzed Suzuki–Miyaura cross-coupling reaction with hindered coupling partners.
