p-Toluenesulfonamide (p-TsNH2) was succesfully employed as an imido ligand precursor in the synthesis of highly air- and moisture-sensitive titanium(IV) and vanadium(IV) complexes. Reaction of M(NMe2)(4) (M = Ti, V) with TsNH2 in toluene afforded [M(mu-NTs)(NMe2)(2)](2) dimer complexes (M = Ti (1), V (2)). By contrast, the reaction carried out in dichloromethane led to [Ti{mu-N,O-NTs}Cl(NMe2)(NHMe2)(2)](2) (3) and [Ti{mu-N,O-NTs}Cl-2(NHMe2)(2)](n) (4) through solvent activation. The same reaction of M(NMe2)(4)/TsNH2 conducted in the presence of an excess of trimethylchlorosilane produced [V(NTs)Cl-2(NHMe2)(2)] (5) and [(Me2HN)Cl2Ti(mu(2)-N-NTs-kappa N-2,O)(2)TiCl2(NHMe2)(2)] (6). Alternatively, compound 6 has also been prepared from TiCl2(NMe2)(2) and TsNH2. 1 was reacted with trimethylchlorosilane to afford the amide complex [Ti{mu-N,O'-N(SiMe3)Ts-kappa N-3,O,O'}Cl-2(NMe2)](2) (7) in which the tosylimide bond has been silylated. Compounds 1-6 represents the first examples of sulfonylimido complexes for titanium and vanadium.
