“…The complex [WH(thf)Cp 2 ](SO 3 CF 3 ) reacts with CS 2 in acetone-d 6 to give the hydride insertion product [W{h 2 -S 2 COCH(CD 3 ) 2 -S,SACp 2 }](SO 3 CF 3 ), for which the crystal structure is reported. 28 Irradiation of [W(CO) 3 HTp Me2 ] in the presence of alkynes produces a range of products that include h 2 -vinyl, h 2 -acyl, metallafuran and carbyne complexes, all thought to be formed via cis insertion of the alkyne into a photogenerated [W(CO) 2 HTp Me2 ] intermediate species. 29 Reactivity of these new hydrides has been explored.…”
