Gold(III) thiosalicylate complexes containing cycloaurated 2-arylpyridine, 2-anilinopyridine and 2-benzylpyridine ligands

Study on carbon–hydrogen activation of ketones by Gold(III) complexes and the synthesis and characterization of two ketonylgold(III) complexes

“…As part of our studies into the chemical and biological properties of Au(III) complexes, we recently reported synthesis of two series of Au(III) complexes with r-bond C,N 2-phenylpyridine and N,N pyrazole or picolinamide ligands through direct deprotonation [20][21][22][23]. The strong polarizing property of Au(III) leads to direct metallation of Au(III) with 2-phenylpyridine under reflux and with pyrazole or picolinamide under mild conditions.…”

Synthesis, characterisation and biological activity of gold(III) catecholate and related complexes

“…[9][10][11] We have found that the thiosalicylate analogue 2 also shows good activity against P388 leukaemia cells, [7] though other derivatives containing alternative cyclo-aurated ligands did not show such good activity. [12] As part of the continuation of our studies in this area, in this paper we report the synthesis and evaluation of complexes containing bidentate, oxygen-donor catecholate ligands.…”

Facile syntheses of four-membered aurathietane dioxide [Au–CHR-SO2-CHR] ring systems, and the first isonitrile insertion reaction into a gold(III)–carbon bond

“…The compounds (2-bp)AuCl 2 (4) [11], (2-anp)AuCl 2 (5) [12], (tolpy)AuCl 2 (6) [13], (MeOdamp)AuCl 2 (2) [14] and PhCOCH 2 SO 2 CH 2 COPh [15] were prepared according to minor modifications of the literature procedures. The sulfone NCCH 2 SO 2 CH 2 CN (Lancaster Synthesis) and aqueous trimethylamine solution (BDH, 25-30%) were used as supplied.…”
