Treatment of W(CO)6with N,N-dichloro-p-toluenesulfonamide affords [W(NTs)2Cl2]x1, which reacts with bipy (2,2′-bipyridine) to give the adduct W(NTs)2Cl2(bipy) 2. The average W - N(imido), W - Cl and W - N (bipy) distances are 1.782, 2.352 and 2.284 Å, respectively. Reaction of [W(NTs)2Cl2]nwith NaTp [Tp = hydrido(trispyrazolyl)borate] gives TpW(NTs)2Cl 4. These tungsten(VI) tosylimido complexes undergo imido transfer reactions with tertiary phosphine to give W(IV) and the N-tosyl phosphinimine.
