    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.
