Sulfamic acid as a green, efficient, recyclable and reusable catalyst for direct addition of aliphatic acid with cyclic olefins
Sulfamic acid has been used as a catalyst for esterification of cyclic olefins with aliphatic acids, and good olefins conversion as well as excellent esters selectivity was obtained. The catalyst could be recycled easily by filtration and directly reused in the next run with satisfactory results.
