Metallkomplexe mit biologisch wichtigen Liganden, CL [1]. 1,1-Dithiolato-Komplex von Palladium(II), Platin(II) und Gold(I) aus Diphenylmethylenglycinester sowie N,N-Dimethylglycinester und Schwefelkohlenstoff

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(I) 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.
