A set of organogold(I) compounds L1-4Au(PPh3), where L1 = [o-C6H4(CH=NC6H 3iPr2-2,6)]- (1), L2 = {o,o-C 6H3[C(Me)=NC6H3Me 2-2,6]2}- (2), L3 = [o,o'-C 6H3(CH2OMe)(CH2NMe 2)]- (3), L4 = [o,o-C6H 3(CH2OMe)2]- (4), were synthesized by the reaction of parent organolithium derivatives L1-4Li with [AuCl(PPh3)] in good yields. The molecular structures of 1-4 were characterized by ESI mass spectrometry and 1H NMR, 13C NMR and 31P NMR spectroscopy, and their structures in the solid state were determined using single-crystal X-ray diffraction analyses. The transmetalation potential of 1-4 was tested by the reaction with either [PdCl2(CH3CN)2] or [PtCl2(Et 2S)2] complexes. While the reaction of compounds 1 and 2 proceeded smoothly with the formation of the desired transition-metal complexes, i.e. (L1PdCl)2 (5), L1PtCl(Et2S) (6) and L2MCl [M = Pd (7) or Pt (8). In the case of the O,C,N- and O,C,O-chelated derivatives 3 and 4 only the platinum(II) compounds L 3PtCl(PPh3) (9) and L4PtCl(Et 2S)2 (10) could be isolated after the reaction, as a result of the labile behaviour of the corresponding palladium compounds. All derivatives 5-10 were characterized by the help of ESI mass spectrometry and 1H NMR, 13C NMR and 31P NMR spectroscopy, and in the case of compounds 5-7 and 9 using single-crystal X-ray diffraction analyses.
