eta(2)-Phosphasilene transition metal complexes - a novel building block for hetero-multimetallic complexes

摘要

Compound eta(2)-((R3SO2Si=PH)-Pt(dmpe) was synthesized by trapping the transient phosphasilene, (R3Si)(2)Si=PH. Novel hetero-bi- and tri-metallic complexes derived from eta(2)-((R3Si)(2)Si=PH)-Pt(dmpe) containing Pt with Li, Zn, Hg and Ag metals were synthesized and characterized by multi-nuclear NMR spectroscop and X-ray crystallography. The synthesis of eta(2)-(R3Si)(2)Si=PH)-Pt(dmpe), and its bonding character are discussed; a 1,2-silyl shift from silicon to phosphorus (a 'Brook-type' rearrangement) within the coordination sphere of a Pt complex is also reported.
