      Abstract
      Using a simple one-pot procedure, reaction of cycloaurated gold(III) dihalide complexes [LAuCl₂] (L = 2-benzylpyridyl, 2-anilinopyridyl) with trisubstituted thioureas PhNHC(S)NR₂ (R = Me, Cy) and Me3N in methanol, followed by addition of excess NaBPh₄ gave the salts [Lau{SC(-NR₂)NPh}]⁺BPH₄⁻ containing N,S-chelated thiourea monoanion ligands. The compounds were obtained in good yields, and were characterised by ESI MS, elemental microanalysis and in two cases by X-ray structure determinations. The series of complexes was extended by additional microscale reactions of LAuCl₂ complexes (L = 2-benzylpyridyl, 2-anilinopyridyl, 2-benzoylpyridyl or picolinamide) with a wide range of trisubstituted thioureas, with products identified by ESI MS.
