Ketenylidenetriphenylphosphorane,Ph3P=C=C=O, reacts with Pt(II) and Pd(II)
3-allyl complexes(allyl = C3H5,2-MeC3H4) to give neutral orcationicmononuclear 1-ketenyl derivatives[M(3-allyl){(1-C(PPh3)(CO)}L]m+(L = Cl, m = 0; L = PPh3, m =1)that have been characterized by elemental analysis, IR,and multinuclear NMR. The X-ray molecular structuredetermination performed on a single crystal of the air-stable derivative[Pt(3-C3H5){1-C(PPh3)(CO)}(PPh3)]BF4 furnishes the first crystallographic evidence ofan1-ketenyl derivative in which the ketene moiety isalsoinvolved in an ylide grouping.
