BECKMANN REARRANGEMENT OF (Z)- AND (E)-OXIMES OF 2-ARYL-4,5,6,7-TETRAHYDRO-6,6-DIMETHYL-2H-BENZOTRIAZOL-4-ONES AND 4,5,6,7-TETRAHYDRO-6,6-DIMETHYLBENZOOXADIAZOL-4-ONES

The synthesis and geometry of (Z)- and (E)-oximes, II and III, derivatives of tetrahydro-2H-benzotriazoles and tetrahydrobenzooxadiazoles, was investigated.The possibility of structural assignments of II and III by Beckmann rearrangement was examined.Some CNDO/2 calculations were also carried out on the oximes II and III.

Lead Tetra-acetate Oxidation of Tris(arylhydrazones) of Cyclohexane-1,2,3-triones

Oxidation of the title compounds with lead tetra-acetate gives 2-aryl-4-arylhydrazono-4,5,6,7-tetrahydro-2H-benzo-1,2,3-triazoles, the corresponding 4-oxo-derivatives, and as minor products 2-aryl-4-acetoxy-4-arylazo-4,5,6,7-tetrahydro-2H-benzo-1,2,3-triazoles, and substituted azobenzenes.The oxidation mechanism is discussed.
