Abstract

[PtCl₂(dppe)] (dppe = 1,2-bis(diphenylphosphino)ethane) reacts with pyrazol-1-yl- (L1), 3,5-dimethylpyrazol-1-yl- (L2), and indazol-1-yl- (L3) dithiocarbamate to form [Pt(L1)₂(dppe)] (1), [Pt(L2) ₂(dppe)] (2) and [Pt(L3)₂(dppe)] (3). These complexes readily transform into [Pt(S₂CO)(dppe)] (4) in chloroform and dichloromethane at room temperature. Stability of the bis(dithiocarbamate) platinum complex from L2, [Pt(L2)₂] (5) suggests that the transformation of 1-3 to 4 is facilitated by the phosphine ancillary ligand.
