Über N,N'-Dialkyl-enhydrazine

Abstract

N,N'-Dialkylhydrazines and cyclohexanone give under the conditions of the enamine preparation octahydrocarbazoles in a Fischer-analogous cyclisation reaction. Dimedone gives the enhydrazine 5a which forms 6 with cyclohexanone. All the products are dehydrogenated by chloranil.
