摘要：

The acid-catalysed reactions of some substituted 2,4-dienones with p-tolylsulphonylhydrazine give 3,4-dihydro-2-tosyl-1,2-diazepines (8); other 2,4-dienones give only the p-tolylsulphonylhydrazones. The dependence of the mode of reaction on the substituents on the dienone, and the role of the acid in promoting the cyclisation have been investigated.
