Аннотация:Abstract von Braun Cyanogen Bromide Reaction Some extensions of von Braun cyanogen bromide reaction have been undertaken on conessine, isoconessine and two simpler bases, dimethyl a-naphthyl amine and diethyl amine. The monocyanamides of conessine and isoconessine yielded acid amides, amino-derivatives (diamines) and guanido derivatives on careful hydrolysis, reduction and treat-ment with ammonia, respectively. The simpler bases also formed the acid amides and dia-mines but failed to give the guanido derivatives under the conditions employed for conessine series. Diamines of all these bases yielded carbinol amines on reaction with nitrous acid.
