The formation of one of one of these compounds is 
The formation of one of one of these compounds is the initial mechanism of the Ugi reaction, after which it is reacted with an isocyanide and a carboxylic acid. The aza modification of the Diels-Alder reaction reacts this functional group with a diene to get a tetrahydropyridine. This functional group is the intermediate in reductive amination, in which it is usually reduced using sodium cyanoborohydride. Alkenes can be reacted with (*) hydrazoic acid to synthesize these compounds in one reaction, and they can also be created by reacting aldehydes or ketones with ammonia. These compounds share a tautomer relation with enamines, and these compounds are synthesized via the Schmidt reaction. When one of this functional group is connected to an aryl or alkyl bond, it is known as a Schiff base. These compounds can be hydrolyzed to form an amine and a carbonyl. For 10 points, name this functional group which contains a carbon double bonded to a nitrogen
