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.

The bonds formed in this reaction are stronger than the bonds broken, making it energetically favorable. The reaction follows a radical chain mechanism similar to radical halogenation reactions,...
Nucleophilic Aromatic Substitution: Addition–Elimination (SNAr)
The reaction begins with an attack of the nucleophile on the carbon that holds the leaving group. This results in the delocalization of the π electrons over the ring carbons. The resonance interaction between the...
