| Abstract | A novel general method for the synthesis of isomeric 3(4)-nitro-4(3)-R-furoxans is developed. 3-Nitro isomers were obtained by reaction of hydroximoyl chlorides with dinitromethane sodium salt followed by conversion of the resulting 1-substituted 1-hydroxyimino-2,2-dinitroethanes into dipotassium (or disodium salts) and their subsequent nitrosation with NaNO2 in AcOH or with N2O4. Thermal isomerization of 3-nitro isomers afforded 4-nitro isomers were prepared in high yields. |
