Abstract: | A series of unsymmetrically substituted furoxans have been prepared from methyinitro-furoxan and a variety of nucleophilic reagents. The nmr study of these compounds and of their parent furazans suggested the structure of 3-methyl derivatives for all the furoxans synthesized: on this ground the 3-methyl structure for methylnitrofuroxan was proposed. On heating some 3-methylfuroxan derivatives, a partial isomerization into the corresponding 4-methyl isomers occurred. |
