Synthesis,Structure,and Hydrophosphorylation of pi-Complexes of Hexacarbonyltungsten(O) with Cyclohexanone,Cyclohexanethione,and N-Cyclohexylideneaniline

摘要

New carbonyl pi-complexes of tungsten(O) with cyclohexanone,cyclohexanethione,and N-cyclo-hexylideneaniline 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.
