Syntheses and characterisation of N,N'-biscarbazolyl azine and N,N'-carbazolyl hydrazine derivatives and their antimicrobial studies.

Abstract

Reaction of 1-oxo-1,2,3,4-tetrahydrocarbazoles 1a-e with hydrazine hydrate in absolute ethanol afforded N,N'-bis-carbazolylazine derivatives 2a-e. Treatment of compounds 1a-e with hydroxylamine hydrochloride in ethanol with a catalytic amount of pyridine resulted in the formation of 1-hydroxyimino-1,2,3,4-tetrahydrocarbazoles 3a-e. Reduction of 3 with… (More)
