0 Abstract. In this paper we derive an implementation of so-called flexible arrays; a flexible array is an array whose size can be changed by adding or removing elements at either end. By representing flexible arrays by so-called Braun trees, we are able to implement all array operations with logarithmic -in the size of the arraytime complexity. Braun trees can be conveniently defined in a recu...

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, aminoderivatives (diamines) and guanido derivatives on careful hydrolysis, reduction and treatment with ammonia, respect...
