Cycloalkenylation of cresols with 4-vinylcyclohexene in the presence of the catalyst Zeocar-2
The optimal conditions were found for the reaction of cycloalkenylation of ortho-, meta-, and paracresols by 4-vinylcyclohexene (4-VCH) in the presence of the industrial catalyst Zeocar-2. It was found that ortho-cycloalkenylation products prevailed, amounting to 78, 64.3, and 46.4 wt % for ortho-, meta-, and paracresols, respectively. The yield of the ortho-cycloalkenylation products was shown to depend on the temperature, 4-VCH : cresol mole ratio, and reaction time.
