Description

General description

N,N-dimethylaniline (DMA) is N,N-disubstituted aniline. The thermo-physical and thermodynamic properties of the binary mixtures of DMA with anisole (ANS) and tert-butyl methyl ether (MTBE) have been reported. In acidic buffers it forms N,N,N′,N′-tetramethylbenzidine at a platinum electrode due anodic oxidation. DMA combines with diazonium salts to form methyl orange under alkaline condition. It forms ortho- and para-nitro derivatives via nitration reaction using N-bromosuccinimide/silver(I) nitrate reagent system in acetonitrile.

Application

N,N-dimethylaniline (DMA) may be used as a catalyst for reductive lithiation.

Reagent in new methodology for symmetrical and unsymmetrical photoconductor squaranes.
