Page/Page column 2, (2011/02/18)
Processes are provided for producing transition metal amides. In methods according to this invention, at least a halogenated transition metal and an amine are combined in a solvent to produce an intermediate composition and an alkylated metal or a Grignard reagent is added to the intermediate composition to produce the transition metal amide.

This invention relates to an improved process to produce metal imino/amino complexes having the formula R1N=M(NR2R3)3where M is a pentavalent metal or (R1N=)2M′(NR2R3)2where M′ is a hexavalent metal. In the process MX5and two-equivalents of primary amine R1NH2or metal hexahalide, M′X6with seven-equivalents of primary amine H2NR1are reacted in the presence of excess pyridine. The resulting reaction product R1N═MX3(py)2or [(R1N)2M′X2(py)]2then is followed by the addition of LiNR2R3. The process provides the final product in high yield and in high purity as well as representing a simplified procedure for synthesizing R1N═M(NR2R3)3or (R1N═)2M′(NR2R3)2type complexes.
