[3+2] Cycloaddition reactions of the phospha-alkyne, (BuCP)-C-t, with a transition metal trisulphide containing terminal thio ligands: syntheses, crystal and molecular structures of [W(eta(5)-(C5Me5)(S)((S2PCBu)-Bu-t)](2) and [W(eta(5)-(C5Me5)(S)(S2C

摘要

The trisulphido complex [PPh4][W(eta(5)-(C5Me5)(S)(3)], reacts with the phospha-alkyne (BuCP)-C-t and O-2 to afford the dimeric complex [W(eta(5)-(C5Me5)(S)((S2PCBu)-Bu-t)](2). Analogous reactions occur with the alkyne Ph2C2 to give [W(eta(5)-(C5Me5)(S)(S2C2Ph2)](2). The molecular structures of both complexes are presented and discussed. (C) 1998 Elsevier Science S.A.
