Hydrazones of aldehydes and ketones undergo to intermolecular cycloaddition to electronnegative olefins via azomethine imines, formed by a formal 1,2-prototropic shift, in low to moderate yield on heating in xylene or ethanol.In some instances the reaction is diverted to give products derived (at least formally) from an ene reaction.Similar intramolecular cycloadditions occur with unactivated terminal alkenes and alkynes.

X=Y-ZH systems are considered in general terms and divided into four classes according to the number of constituent atoms that possess lone pair electrons.Those systems in which the central Y atom possesses a lone pair are shown to be capable of participa
