Cyclometallated gold(III) complexes derived from 2-benzylpyridine, 2-anilinopyridine [AuCl2(C5H4N-X-C 6H4)] [X = CH2 (2-bp) or NH (2-anp)] or 2-p-tolylpyridine (tolpy) [AuCl2(C5H4NC 6H3CH3)] react with the sulfones RCH 2SO2CH2R (R = CN or COPh) in hot methanol with added trimethylamine base to give new aurathietanedioxide complexes containing the Au(CHRSO2CHR) four-membered ring system. The previously reported cyclo-aurated dimethylbenzylamine (MeO-damp) complex [Au{CH(COPh)SO 2CH(COPh)}(Me2NCH2C6H 3OMe)] was also synthesised by this method, and found to exist as a mixture of major (trans) and minor (cis) isomers with respect to the orientation of the COPh substituents across the four-membered ring. The reaction of one complex with tBuNC in refluxing dichloromethane results in insertion of the isonitrile into the Au-C bond trans to the phenyl ring, followed by proton transfer. An X-ray crystal structure determination on this product was carried out.
