The Versatility of Tertiary Phosphane Ligands in Coordination and Organometallic Chemistry

Abstract

Abstract Tertiary phosphanes form kinetically stable complexes with formal oxidation states of the metal ranging from + IV to −I (“electronic versatility”). Variously substituted phosphanes and polydentate, chelate forming phosphanes and polyphosphanes can be synthesized (“steric versatility”). Studies on complexes containing such ligands provide, inter alia , useful information about the metal‐phosphorus bond, about the steric effects of the phosphane ligand, and about reactions of coordinated phosphanes.
