Abstract

The reagents 1,2-C6H4(CH=NR)(SMe), R = CH2CH2NMe2 or Ph, react with [Pt2Me4(μ-SMe2)2] by oxidative addition of the aryl-sulfur bond to give the corresponding crystalline binuclear platinum(IV) compounds [Pt2Me4(μ-SMe)2(κ(2)-C,N-C6H4-2-CH=NR)2], as the isomers with Ci (R = CH2CH2NMe2 or Ph) or C1 (R = Ph) symmetry. These first examples of C-S bond activation at platinum(II) occur easily at room temperature, and the reactions give complex equilibria of isomeric products, from which the isolated compounds crystallise.
