Abstract

In the reaction of benzofurazan with isopropanol and cyclohexanol o-nitrosoaalkylaminobenzenes are formed besides 2,2-dialkyl-2H-benzimidazole-oxides. In the instance of 4-aminobenzofurazan only 2-nitroso-3-alkylaminoanilines are obtained. 5-Nitrobenzofurazan reacts with isopropranol in sulfuric acid to form 4-nitro-2-nitrosoisopropylaminobenzene; however, in the instance of 4-nitrobenzofurazan derivatives the formation of o-nitrosoalkylaminobenzenes has not been observed.
