A series of compounds of the type trans-(amine)PtCl2(C2H4) (amine = phenazine, quinoxaline, pyrazine, phenazine N-oxide, 2,6-dimethylpyrazine, tetramethylpyrazine, acridine) was prepared by displacement of chloride from PtCl3(C2H4)-. (phenazine)PtCl2(C2H4) is an effective hydrosilation catalyst. It reacts with L (L = styrene, Ph3P, Ph3As) to form (phenazine)PtCl2L and (phenazine)[PtCl2L]2. Pyrolysis leads to (phenazine)2(PtCl2)2(C2H4). Reduction of (phenazine)PtCl2(C2H4) to form [(phenazine)PtCl2(C2H4)]2 -·, whose ESR spectrum is discussed, was found by double-potential-step chronocoulometry to proceed by an ECE mechanism. The platinum-catalyzed reduction by hydrogen yields H[(phenazine)PtCl2(C2H4)]2. Reduction by silanes, R3SiH, in CHCl3 produces H3[(phenazine)PtCl2(C2H4)] 3PtCl3. Characterization of these compounds by X-ray photoelectron spectroscopy is discussed.
