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-Me2, 4-Prn, 4-But) 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 ...
