High Quality Content by WIKIPEDIA articles! The Von Braun reaction is an organic reaction in which a tertiary amine reacts with cyanogen bromide to an organocyanamide . An example is the reaction of dimethyl- -naphthylamine The reaction mechanism consists of two nucleophilic substitutions: the amine is the first nucleophile displacing the bromine atom which then acts as the second nucleophile Organic reactions are chemical reactions involving organic compounds. The basic organic chemistry reaction types are addition reactions, elimination reactions, substitution reactions, pericyclic reactions, rearrangement reactions and redox reactions. In organic synthesis, organic reactions are used in the construction of new organic molecules.
