摘要
Four alkoxo tungsten complexes [Cp 2W(PMe 3)OR] +OTs -(R=Me,Et, n Pr, i Pr) and monohydrido tungsten complex [Cp 2W(H)(PMe 3)] +OTs - were synthesized and characterized by IR, 1H NMR and elemental analysis. The β elimination of these complexes in dimethyl sulfoxide solvent yields monohydrido tungsten complex [Cp 2W(H)(PMe 3)] +OTs - and a ketone or aldehyde.
