Abstract
The N,N-dibrominated amines easily can be prepared by reaction of the corresponding amines with heterocyclic N-bromo imides. Some properties and reactions are given. As just reported they show a thermal instability. Only three compounds could be prepared in pure critalline state: CH3NBr2 (until now just known as a solution), Br2NCH2CH2NBr2 and (CH3)3CNBr2. The last one shows a superior stability and was investigated more exactly.
According to:
for the first time a cristalline N-monobromomonoalkylamine was prepared. Comparison with the acyl derivatives of dibromoamine shows a partly differing behaviour of the alkyl derivatives, which is explained by differences in the polarisation of the N−Br bonding.
