, 2004 Reactions of hydrazonoyl halides with imidazoles and benzimidazoles
Journal of the Chemical Society, Perkin Transactions 1, 1979Hydrazonoyl halides upon reaction with N-methylimidazole and N-substituted benzimidazoles yield ring opened 1 : 1 adducts. The action of aqueous sodium hydroxide on these adducts leads to the formation of pyrazin-2-one or quinoxalin-2-one derivatives via ring expansion.

Hydrazonoyl Halides as Precursors for New Fused Heterocycles of 5α‐Reductase Inhibitors
Archiv der Pharmazie, 2011AbstractA new series of benzo[6,7]cyclohepta[1,2‐d]triazolo[4,3‐a]pyrimidines 8a–l was synthesized via reaction of heterocyclic thione 4 or its methyl derivatives 10 with hydrazonoyl halides 5a–l. Also, reaction of compound 4 with a mixture of chloroacetic acid and aromatic aldehyde derivatives gave benzo[6,7]cyclohepta[1,2‐d]thiazolo[3,2‐a]pyrimidin‐3‐
