Abstract
Gold(III) bromide reacts with NMe 2CH 2Ph to give [AuBr 3(NMe 2CH 2Ph)], [NMe 2(CH 2Ph)H][AuBr 4] or [NMe 2(CH 2Ph)H][AuBr 2] depending on the reaction conditions, with azobenzene to give [AuBr 3(azobenzene)] and with 2-vinylpyridine to give [AuBr 3 (2-vinylpyridine)] which with bromine gives [AuBr3 ? 2-(1,2-dibromoethyl)pyridine]. Unsuccessful attempts to rearrange these complexes to the products of auration of the aryl- or vinyl-substituents of the ligands are described. Evidence is presented that the product of reaction of allyl methyl sulphide with gold(III) bromide arises from bromoauration of the allylic group.
