摘要：

The 1,1-dithiolates Ph2C=N-C(CO2Et)=CS22- and Me2NC(CO2Et)=CS22- from diphenylmethylene glycine ethylester or N,N-dimethylglycine ester and CS2 react under basic conditions with chlorophosphine compounds of Pd(II), Pt(II) and gold(l) to give the complexes Ph2C=N-C(CO2Et)=CS2ML2, Me2N-C(CO2Et)=CS2ML2 (M = Pd, Pt; L = PPh3, 2L = Ph2PCH2CH2PPh2) and Ph2C=N-C(CO2Et)=CS2(AuPPh3)(2), and Me2N-C(CO2Et)=CS2 (AuPPh3)(2). The structures of the palladium complex Ph2C=N-C(CO2Et)=CS2Pd(PPh3)(2) and of diphenylmethylene-L-alanine ethylester were determined by X-ray diffraction. Besides this S,S-complex also the (less stable) S,O-isomer could be detected.
