FORMATION OF o-NITROSOALKYLAMINOBENZENES IN THE REACTION OF BENZOFURAZAN S WITH ALKOHOLS IN ACIDIC CONDITIONS

Article abstract of DOI:10.1007/BF01373555

In the reaction of benzofurazan with isopropanol cyclohexanol o-nitrosoalkylaminobenzenes 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 isopropanol 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.
