1,4‐benzothiazine derivatives from 2‐aminobenzenethiol and hydrazonoyl halides
Journal of Heterocyclic Chemistry, 1983Abstract2‐Aminobenzenethiol was condensed with alkyl α‐chlorophenylhydrazonoglyoxylates yielding alkyl 2‐(2‐aminophenylthio)‐2‐arylhydrazonoglyoxylates which were cyclized to the corresponding 2‐arylhydrazono‐2,3‐dihydro‐4H‐1,4‐benzothiazin‐3‐ones.

The Chemistry of Heterocyclic Hydrazonoyl Halides
1995Publisher Summary Hydrazonoyl halides have emerged as an important class of intermediates, particularly for the synthesis of heterocyclic compounds. This chapter discusses the synthesis, properties, and reactions of Hydrazonoyl Halides. The mechanisms of some of the reactions and the structures of some of the products are outlined.

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‐

REACTION OF HYDRAZONOYL HALIDES WITH 2,4-DIOXOTETRAHYDROTHIAZOLE-5-THIOCARBOXANILIDES
Phosphorus, Sulfur, and Silicon and the Related Elements, 1995Abstract Reaction of 3-phenyl-2,4-dioxotetrahydrothiazole-5-thiocarboxanilides 3 with hydrazonoyl halides 4 in N,N-dimethylformamide in the presence of potassium hydroxide yielded the thiadiazoline derivatives 7 and 13. The mechanism of formation of the latter products is discussed.

Reactions and Biological Activities of Hydrazonoyl Halides
Current Organic SynthesisAbstract: This review covers the literature information on the chemistry of hydrazonoyl halides with different substrates to give heterocyclic compounds. From the foregoing survey, it seems this provides a useful and convenient strategy for the synthesis of numerous heterocyclic derivatives.
