Abstract

The reaction of [W(≡CR)(CO)₂(η-C₅H ₅)] (R = C₆H₃Me₂-2,6) with thionyl chloride provides the metallacyclic alkylidene complex [W(=CRSCRS)Cl ₃(η-C₅H₅)], while similar treatment of [W(≡CR)(CO)₂{HB(pz)₃}] (pz = pyrazol-1-yl) provides the alkylidyne complex [W(≡CR)Cl₂{HB(pz)₃}], which is also obtained from the reaction of [W(≡CR)(CO)₂{HB(pz) ₃}] with [Fe(η-C₅H₆)2]Cl. The crystal structures of [W(≡CC₆H₂Me₃-2,4,6)(CO) ₂{HB(pz)₃}], [W(=CRSCRS)Cl₃(η-C ₅H₅)], and [W(=CR)Cl₂{HB(pz)₃}](R = C₆H₃Me₂-2,6) are reported.
