Including such types as Schiff bases and azomethines, for 10 points, identify these functional groups that are characterized by a carbon-nitrogen double bond.
In the Povarov reaction, an aromatic one of these compounds reacts with an electron-rich alkenol molecule in order to form a quinoline. Tetrahydropyrines can be formed from a molecule of this type and a diene in the Aza modification of the Diels-Alder reaction. When used in an addition reaction with a secondary amine, an ionic salt of this type of compound is formed and can further react to create a Mannich base. They can be formed from the use of hydrozoic acid and alkenes in one version of the Schmidt reaction.
