This process is usually a side reaction, and conversion of dialkylbenzenes into the corresponding para-or ortho-alkylnitrobenzenes does not exceed 10317%. Most often the nitrodealkylation occurs at nitration of dialkylbenzenes containing isopropyl [133] or tert- butyl [3, 4] groups. As to replacement with the nitro group of methyl or ethyl, it was observed only once in nitration of para-methyl-and para-ethylphenylcyclopropanes [3]. We found ...
