PLATINUM-GROUP METAL FUNCTIONALIZED PHOSPHINE COMPLEXES .2. PHOSPHINOAMIDE RHODIUM(I), IRIDIUM(I), PALLADIUM(II) AND PLATINUM(II) COMPLEXES

Rhodium(I), iridium(I), palladium(II) and platinum(II) complexes of th e phosphinoamide ligands, Ph2PCH2CONHR (R = H, HDPA; Me, MDPA; Ph, PDP A) were prepared and characterized by using conductivity data, i.r., H -1 and P-31 (H) n.m.r. spectral data. Reaction of the ligands with MCl (PPh3)3 and MCl(CO)(PPh3)2 (M = Rh, Ir) in CH2Cl2 under reflux lead to the formation of MCl(PPh3)2Ph2PCH2C(O)NHR] and MCl(CO)(PPh3)[Ph2PCH2C (O)HNR] respectively. The reaction of either K2MCl4 or Cis-MCl2(PPh3)2 affords complexes of the type cis-MCl2[Ph2PCH2C(O)NHR]2 (M = Pd, Pt). A similar product results even from the reaction of phosphinoamides w ith cis-platin. Possible structures are proposed for the complexes bas ed on their physicochemical data.
