Pentakis(dimethylamido)tantalum is an organometallic compound of tantalum. It is a colorless solid that is soluble in organic solvents. It hydrolyzes readily to release dimethylamine.
Ta(NMe2)5 is prepared by treating TaCl5 with lithium dimethylamide.[1] The preparation is similar to that for tetrakis(dimethylamido)titanium.
The compound has idealized D3h symmetry (ignoring the organic substituents).
The complex effects C-alkylation of secondary amines with 1-alkenes [2] and hydroaminoalkylation of olefins to form alkylamines.[3]
