Abstract

4, 4′-Diphosphinobiaryls and 1, 3-and 1, 4-borylphosphinobenzenes carrying crowded triarylphosphine moieties were synthesized by reaction of the corresponding diarylchlorophosphine with an arylcopper (I) reagent. Intramolecular interaction of the phosphorus redox center with the other phosphorus or the boron redox center was investigated by cyclic voltammetry. 4, 4′-Diphosphinobiaryls displayed two-step ...
