Various pentacarbonyl complexes of W and Cr containing heterocyclic ligands were prepared from the synthon formed by the addition of PhC≡CXLi (X = S or Se) to carbene complexes [M(CO)5{(C(OEt)Ph}] (M = Cr, W). The nature of the electrophile (S or Se) that was added, as well as the temperature at which the reaction was carried out, determined whether the synthon acted mainly as an anionic thio- or selenocarbene complex to give rise to carbene complexes [W(CO)5L] (L = CC(Ph)=C(Ph)SeS, CC(Ph)-=C(Ph)SSe, CC(Ph)=C (Ph)SeSe) or as a thio- or selenoacyl anion to form thione or selone complexes [Cr(CO)5{S=CC(Ph)=C(Ph)SS}] and [W(CO)5L] (L = S=CC(Ph)=C(Ph)SS, Se=CC(Ph)=C(Ph)SS, Se=CC(Ph)=C(Ph)SeSe).

The adduct between pentacarbonyl-α-ethoxybenzylidenetungsten and lithium phenylethynethiolate is a promising nucleophilic reagent for the preparation of a variety of compounds such as tungsten co-ordinated 2,3-diphenyl-3-ethoxypropenethial (1), 4,5-diphen
