Technology Process of (Tert-butylimino)tris(dimethylamino)tantalum

There total 3 articles about (Tert-butylimino)tris(dimethylamino)tantalum which guide to synthetic route it. The literature collected by LookChem mainly comes from the sharing of users and the free literature resources found by Internet computing technology. We keep the original model of the professional version of literature to make it easier and faster for users to retrieve and use. At the same time, we analyze and calculate the most feasible synthesis route with the highest yield for your reference as below:

synthetic route:

Reference yield: 37.0%

lithium tert-butylamide (37828-54-9) + lithium dimethylamide (3585-33-9) + tantalum pentachloride (7721-01-9) → tetrakis(dimethylamino)tantalum chloride (1092381-62-8,82482-88-0) + (tert-butylimido)tris-(dimethylamido)tantalum(V) (69039-11-8)

Guidance literature:

In hexane; byproducts: LiCl, (CH3)2NH; under N2, TaCl5, LiN(CH3)2, LiNHC(CH3)3 in hexane were stirred for 48 h; mixt. was filtered, soln. was evapd., residue was sublimed, product wasrecrystd. from hexane; elem. anal.;

Reference yield:

pentakis(dimethylamido)tantalum (19824-59-0) + tert-butylamine (75-64-9) → (tert-butylimido)tris-(dimethylamido)tantalum(V) (69039-11-8)

Guidance literature:

In hexane; to Ta(N(CH3)2)5 in hexane was added t-BuNH2, mixt. was stirred for 60 h; solvent was evapd., residue was sublimed, recrystd. from hexane (-35°C);
