In an acidified chloroform solution, bicyclic C-azo-N-(N-hetaryl)aziridines are converted to bicyclic 2H-1,2,3-triazoles. This transformation can occur on the surface of silica gel, and also during storage of these compounds at room temperature. 2005 Spri
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.

The thermal base-catalysed and photochemical transformation (Boulton-Katritzky rearrangement) of the title tetrahydrobenzooxadiazoles to tetrahydro-2H-benzotriazoles is studied.Attempts to induce analogous rearrangement in tetrahydro-2H-benzotriazol-4-one arylhydrazones or oximes failed.Some CNDO/2 calculations are also carried out.
Lead Tetra-acetate Oxidation of Tris(arylhydrazones) of Cyclohexane-1,2,3-triones

, p. 1076 - 1100 (2007/10/02)
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.
