Cycloaurated gold(III) complexes with monoanionic thiourea ligands
摘要:
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-benzyl-pyridyl, 2-anilinopyridyl, 2-benzoylpyridyl or picolinamide) with a wide range of trisubstituted thioureas, with products identified by ESI MS.

thioureas via a formal π-insertion into the C═S bond. The reaction contrasts with that of ureas, which proceeds via benzyne σ-insertion into the C–N bond, and represents a new, operationally simple route to functionalized amidines.
A variety of substituted thioureas result from thiuram disufides by a simple reaction with different amines.

Abstract Reaction of nickel(II) acetate, 1,2-bis(diphenylphosphino)ethane (dppe), and a di- or tri-substituted thiourea R1NHC(S)R2R3 (R3 = H or alkyl) with trimethylamine in hot methanol gave cationic nickel(II) complexes containing N,S-chelated thiourea monoanion ligands [NiSC(NR2R3)NR1}(dppe)]+, which can be readily isolated as their BPh4− salts. The X-ray crystal structure of [NiSC(NMe2)NPh}(dppe)]+BPh4−
