Reaction of Pt(Ph3P)2C2H4 with p-tolyl isoselenocyanate yields the first known example of a ?-bound organic isoselenocyanate ligand in the complex Pt(η²-SeCNC7H7)(Ph3P)2.Reaction of this complex with methyl iodide results in alkylation at the selenium atom rather than at nitrogen, with resultant loss of selenium to yield PtI2(CNC7H7)(Ph3P) as the final product.If the reaction of Pt(Ph3P)2C2H4 with p-tolyl isoselenocyanate is carried out in CH2Cl2 solution, selenium abstraction occurs and the complex Pt(η²-Se2CNC7H7)(CNC7H7)(Ph3P) is formed which contains both an isonitrile ligand and the as yet unreported diselenocarbonimidato ligand.Alkylation of this ligand failed to yield a diselenocarbamate complex.
