摘要：

ortho-Mercurated derivatives of several substituted 2-phenylpyridines and of 2-phenyl-4-(methylcarboxylato)quinoline have been prepared and characterised. C,N-chelated gold(III) derivatives, [AuCl2(C6H4C5H3RN)] (R = H, 3-Me, 3,5-Me-2, 4-Pr-n, 4-Bu-t) are prepared more efficiently by trans-metallation reactions than by direct reaction of AuCl4- with the phenylpyridines. The new gold complexes were characterised spectroscopically and a variety of substitution reactions have been effected. As is usual with unsymmetrical bidentate ligands, the softer donor atom is found trans to the N-donor of the pyridine unit. Crystal-structure determinations are reported for [Au(OAc)(pmpy)(py)]ClO4, [Au(ppy)(dpbt)]BPh4, [Au(ppy)(S2CNMe2)]BPh4 and AuCl(pqcm)(2) [Hppy = 2-phenylpyridine, Hpmpy = 2-phenyl-3-methylpyridine, Hpqcm = 2-phenyl-4-(methylcarboxylato)quinoline].
