Article abstract of DOI:10.1016/S0022-328X(00)87650-0

The preparation and reactivity of two carbon disulfide complexes of tungsten, W(CO)3(R2PC2H4PR2)CS2 (R = CH3, C6H5) are described.Electrophiles (MeI, W(CO)3(R2PC2H4PR2)) add at the exocyclic sulfur, nucleophiles react with CS2 substitution (pyridine, P(OR)3), sulfur abstraction, or addition at carbon (PR3).Towards N3^- the coordinated CS2 acts as a dipolarophile, where as with acetylene dicarboxylic ester it reacts as a 1,3-dipole to give a dithiocarbene derivative.
