The reaction of [W(⋮CR)(CO)<sub>2</sub>(η-C<sub>5</sub>H<sub>5</sub>)] (R = C<sub>6</sub>H<sub>3</sub>Me<sub>2</sub>-2,6) with thionyl chloride provides
the metallacyclic alkylidene complex [W(CRSCRS)Cl<sub>3</sub>(η-C<sub>5</sub>H<sub>5</sub>)], while similar treatment
of [W(⋮CR)(CO)<sub>2</sub>{HB(pz)<sub>3</sub>}] (pz = pyrazol-1-yl) provides the alkylidyne complex [W(⋮CR)Cl<sub>2</sub>{HB(pz)<sub>3</sub>}], which is also obtained from the reaction of [W(⋮CR)(CO)<sub>2</sub>{HB(pz)<sub>3</sub>}] with
[Fe(η-C<sub>5</sub>H<sub>5</sub>)<sub>2</sub>]Cl. The crystal structures of [W(⋮CC<sub>6</sub>H<sub>2</sub>Me<sub>3</sub>-2,4,6)(CO)<sub>2</sub>{HB(pz)<sub>3</sub>}], [W(CRSCRS)Cl<sub>3</sub>(η-C<sub>5</sub>H<sub>5</sub>)], and [W(⋮CR)Cl<sub>2</sub>{HB(pz)<sub>3</sub>}](R = C<sub>6</sub>H<sub>3</sub>Me<sub>2</sub>-2,6) are reported.
