By reaction of Pt(PPh3)2O2 with {A figure is presented} ethanol the complexes Pt(PPh3)2 {A figure is presented} (R = R′ = H; R = H, R′ = NO2; RR′ = {A figure is presented} obtained. The analogous derivatives isolated from Pt(PPh3)2O2 and the ortho-diamines with R = H, R′ = Me or R = R′= Me, showed some peculiar spectroscopic properties. A related reaction has been carried out with {A figure is presented} being isolated; the latter was also obtained from cis-Pt(PPh3)2Cl2 and {A figure is presented} in a basic medium. The platinum diamido complexes can be reversibly protonated with HBF4 to give [Pt(PPh3)2 {A figure is presented} (BF-4)2 H2O Attempted reactions of Pt(PPh3)2O2 with NH3, NH2CH2CH2NH2 an p-RC6H4NH2 (R = Me, OMe, NO2) did not give well characterizable products, while with But-NH2 an already known cluster complex was obtained.
