Synthesis and structure of the dimericdiorganotinhydroxyphosphinate [t-Bu2Sn(OH)OPPh2O)]2

Abstract

The reaction of (C6F5)3BOPPh2OH (prepared in situ from the rather weak Brønsted acid Ph2PO2H and the strong Lewis acid B(C6F5)3) with (t-Bu2SnO)3 provided the dinuclear complex [t-Bu2Sn(OH)OPPh2O)]2, which was investigated by X-ray crystallography.
