THE SYNTHESIS OF TRISELENOCARBONATE COMPLEXES OF PLATINUM

Abstract

The addition of dichloromethane solutions of carbon diselenide to liquid ammonia containing suspensions of platinum bis-phosphine dichlorides [PtCl₂(PR_X)_n] (n = 2, (PR_X) = PMe₃, PMe₂Ph, PMePh₂, and PPh₃, n = 1, (PR_X) = dppm, dppe, dppp, dppf) gives, after evaporation of the ammonia and extraction of the reaction residues with dichloromethane, the appropriate platinum bis-phosphine triselenocarbonate complexes in reasonable yields (40–60%).
