Abstract

Abstract ω-Azolylacetophenones 1 and 2 react with dimethylformamide dimethylacetal to yield enaminones 7, 8 that were converted into azolylazoles via reaction with hydrazine and with hydroxylamine. Compounds 1, 2 also coupled with aromatic diazonium salts to yield arylhydrazones and reacted with nitrous acid to yield corresponding oximes.
