Extra Details:: Cyanogen bromide is a versatile solid reagent which is used widely in organic synthesis and biochemistry. Cyanogen bromide is usually written as CNBr, though this is misleading as the carbon atom has a triple bond to nitrogen and a single bond to bromine (N�C-Br). The electronegative bromine and nitrogen atoms shift electron density away from the carbon atom in this linear molecule, making it particularly electrophilic and susceptible to nucleophilic attack. The reagent has many uses in synthetic organic chemistry, being useful for the synthesis of guanidines, hydroxyguanidines, heterocyclic systems, ureas and thioureas.1 CNBr is a source of electrophilic cyanide, and reacts with primary and secondary amines to yield cyanamides (1), which can be reacted further with amines or hydroxylamines to yield guanidines (2) and hydroxyguanidines (3) respectively..
