Synthesis, structure, and hydrophosphorylation of π-complexes of hexacarbonyltungsten(0) with cyclohexanone, cyclohexanethione, and N-cyclohexylideneaniline

Abstract

New carbonyl π-complexes of tungsten(0) with cyclohexanone, cyclohexanethione, and N-cyclohexylideneaniline were synthesized. Geometric and electronic parameters of the ligands, as well as energy parameters of the complex formation process, were determined by quantum-chemical calculations. Hydrophosphorylation with diethyl phosphonate changed the reactivity of coordinated N-cyclohexylideneaniline, while no analogous effect was observed for cyclohexanone and cyclohexanethione. © 2005 Pleiades Publishing, Inc.
