Mechanism of catalytic hydrogenation of nitrobenzene in an aprotic medium in the presence of quinones

Conclusions The hydrogenation of nitrobenzene in an aprotic medium in the presence of quinones is realized by a reduction-protonation mechanism through alternating stages of electron transfer and protonation. The function of proton donor is fulfilled by the corresponding hydroquinones formed from the quinones under the reaction conditions.Translated from IzvÉstiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 7, pp. 1500–1505, July, 1981.
