Abstract

Reactions of Perfluoro(5-aza-4-nonene) with Hydrazine and Some of Its Derivatives.-The title azanonene (I) reacts with hydrazines to furnish triazole derivatives. In the case of (V), deprotected triazole (VII) is obtained instead of the expected (VI). The perfluoroolefin analogue (VIII) behaves like (I) in reactions with arylhydrazines and propionylhydrazine, but provides isomeric hydrazones in the reaction with hydrazine hydrate. Attempts to effect cyclization of these products into expected pyrazole derivatives by action of Et 3 N result in formation of cyclobutadiene derivatives (XII)/(XIII). -(FURIN, G.
