- Reaction of 1,2-dibromoethane with primary amines: Formation of N,N′-disubstituted ethylenediamines RNH-CH2CH2-NHR and homologous polyamines RNH-[CH2CH2NR]n-H
-
The reaction of primary amines RNH2 (R: Me, Et, iPr, tBu and Ph) with 1,2-dibromoethane gave N,N′-disubstituted ethylenediamines R-NH-CH2CH2-NH-R (1) in yields ranging from 10% (1a; R=Me) to 70% (1d, R=tBu; 1e, R=Ph). Pipe

- A synthetic route to poly-N,N'-dimethylethylenediamines
-
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.
