The reaction between the title compounds and hydrazine hydrate in an appropriate carboxylic acid gave 1-acyl/aroyl-3-aryl-4-methyl-4,5-dihydropyrazoles 9, instead of 2,5,6-trisubstituted 6,7-dihydro-1,3,4-oxadiazepines as previously reported.Evidence is presented for the attribution of the correct structure and for the reaction mechanisms involved.
