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 aromaticdiazoniumsalts to yield arylhydrazones and reacted with nitrous acid to yield corresponding oximes.
