Preparation of metallacyclosulphones of nickel, palladium, and platinum and the X-ray crystal structure of trans-2,4-diphenyl-1,1-bis(triphenylarsine)platinathietane-3,3-dioxide
Abstract
A variety of metallathietane-3,3-dioxides of platinum(II), palladium(II), and nickel(II), [[graphic omitted]HPh}L2] are formed in high yield by the action of the dianion [PhCHS(O)2CHPh]2– upon either cis- or trans-[MCl2L2]; the X-ray structure of the title compound (1a) establishes the presence of a puckered platinathietane-3,3-dioxide ring with no substantial Pt ⋯ S transannular bonding.
