Synthesis of some d0 organoimido complexes of the early transition metals
Nugent, William A.

A series of d0 tert-alkylimido complexes has been prepared for the group 5-7 transition metals. The complexes have the general formula M(NR)nX4-n where X is a monoanionic ligand and R is a tertiary alkyl group. Complexes where M = Nb, Ta, or W were prepared by in situ deprotonation of tert-alkylamido ligands. Complexes where M = V, Cr, Mo, or Re were prepared by treatment of the metal oxide or oxychloride with the corresponding tert-alkyl(trimethylsilyl)amine. Ligand exchange and insertion reactions gave access to a range of X ligands; examples include complexes with OR, OSiR3, NHR, NR2, S2CNR2, CH3, Cl, and Br substituents.
