Dimethylbenzylamine


Dimethylbenzylamine is the organic compound with the formula C6H5CH2N2. The molecule consists of a benzyl group, C6H5CH2, attached to a dimethylamino functional group. It is a colorless liquid. It is used as a catalyst for the formation of polyurethane foams and epoxy resins.

Synthesis

N,''N''-Dimethylbenzylamine can be synthesized by the Eschweiler–Clarke reaction of benzylamine

Reactions

It undergoes directed ortho metalation with butyl lithium:
Via these reactions, many derivatives are known with the formula 2-X-C6H4CH2N2.
The amine is basic and undergoes quaternization with alkyl halides to give quaternary ammonium salts:
Such salts are useful phase [transfer catalyst]s.

Uses

As the molecule has tertiary amine functionality, two of the key uses are as an epoxy-amine cure enhancement catalyst and also as a polyurethane catalyst.
