  Mechanistic Study on the Insertion of Phenylacetylene into cis-Bis(silyl)platinum(II) Complexes

  摘要：

  Four bis(silyl)platinum complexes cis-Pt(SiR3)(2)(PMe2Ph)(2) (SiR3 = SiMe2Ph (la), SiMePh2 (Ib), SiPh3 (Ic), SiFPh2 (Id)) have been prepared and their reactions with alkynes and alkenes examined. The X-ray structures of 1a-c exhibit significant distortion from the square planar geometry in the order Ib > Ic > la. Complexes 1a-d react with phenylacetylene in solution to give the corresponding insertion complexes cis-Pt{C(Ph)=CH(SiR3)}(SiR3)(PMe2Ph)(2) (2a-d). Complex Ic reacts also with acetylene to afford the insertion complex cis-Pt(CH=CHSiPh3)(SiPh3)(PMe2Ph)(2) (2e), whose structure has been determined by X-ray diffraction study. Kinetic studies indicate the insertion process involving prior dissociation of PMe2Ph ligand from 1, followed by insertion of phenylacetylene into the Pt-SiR3 bond. The reactivity toward insertion decreases in the order Ic > la > Ib much greater than Id. Factors responsible for the reactivity order are discussed on the basis of kinetic data and X-ray structures.
