A synthetic route to poly-N,N'-dimethylethylenediamines
Tuladhar,D'Silva
, p. 2203 - 2206 (1992)
A simple high yielding synthesis of poly-N,N'-dimethylethylenediamines has been achieved by the alkylation of readily available N-methylamine or N,N'-dimethylethylenediamine with N-methyl-N-(4-toluenesulphonyl)iodoethylamine.
