Bromoaroylmethylidenephosphoranes 3 are reacted with aryl-and hetarylboronic acids under Suzuki-Kumada conditions to yield biaryl- and arylhetaryl-carbonylmethylidenephosphoranes 4. The reaction can also be run in a one-step procedure from (boromoaroylmethyl)triphenylphosphonium bromides 2. 4 are air-stable phosphoranes that undergo Wittig olefination reactions with aldehydes under benzoic acid catalysis.
