“…48 The N-alkylation of benzimidazole was also effectively performed, under MW activation, over basic carbon catalysts selectively yielding the corresponding alkylated heterocyclic compound in a high yield in very short reaction times (75% in only 5 min of reaction time). 49 Furthermore, the imidazole alkylation reaction, under ultrasound activation, was also investigated by some of Scheme 9 Proposed reaction courses for the dehydrogenation of EB to ST under CO 2 .…”
