The Uses of Tribenzylamine

Tribenzylamine (TBA) is a tertiary amine which can be used :

As a nitrogen group source for the reactions involving C?N bond formation.
For the synthesis of imine i.e. N?benzylidene benzylamine by aerobic oxidative condensation.
As an extractant for the separation and determination of Cr(VI) and Cr(III) from wastewater.

TBA can also undergo debenzylation in the presence of ceric ammonium nitrate (CAN) to form dibenzylamine.

Purification Methods

Crystallise the amine from absolute EtOH or pet ether. Dry it in a vacuum over P2O5 at room temperature. The hydrochloride has m 226-228o (from EtOH) and the picrate has m 191o (from H2O or aqueous EtOH). [Beilstein 12 IV 2183.]
