| Abstract: | Conclusions A number of azo derivatives of 2,6-diphenyl-1,4-benzoquinone diazide have been prepared. In the crystalline state, these generally exist in the azophenol form. After prolonged standing in CDCl3 solution, they slowly isomerize to the hydrazo form, an equilibrium being established.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 2, pp. 405–408, February, 1979. |
