Selectivity of the Cycloaddition of Tert-amyl Alcohol and α-methylstyrene

Abstract:

1,1,2,3,3-Pentamethylindane was synthesized by alkylation of tert-amyl alcohol and α–methylstyrene (AMS) using sulfuric acid and sulfolane as catalyst. The effect of the volume of sulfolane on the selectivity for the cross-dimerization as compared to the dimerzation of the AMS was studied. The result shows that the selectivity increased by 32% after adding even 1 ml of sulfolane as solvent.
