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
A variety of metallathietane-3,3-dioxide of platinum(II), palladium(II), and nickel(II), are formed in high yield by the action of the dianion (PhCHS(O)2CHPh>(2-) upon either cis- or trans-; 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.
