The preparation and structures of metallathietane-3-oxides and –3,3-dioxides of platinum and palladium: the crystal structures of trans-2,4-dibenzoyl-1,1-bis(triphenylphosphine)platinathietane-3-oxide and trans-2,4-dibenzoyl-1,1-bis(triphenylphosphine)platinathietane-3,3-dioxide

Abstract

High yields of platinathietane-3-oxides and metallathietane-3,3-dioxides may be obtained by treatment of [MCl₂L₂] with [RCH₂S(O)_nCH₂R](n= 1, R = COPh; n= 2, R = COPh or CO₂Me) and silver(I) oxide; single crystal X-ray studies on the title complexes establish the presence of puckered metallacycles, the sulphinyl oxygen of the platinathietane-3-oxide adopting an equatorial environment.
