Bp. Bandgar et Sp. Kasture, Natural kaolinitic clay: a remarkable reusable solid catalyst for the selective cleavage of thioacetals without solvent, GREEN CHEM, 2(4), 2000, pp. 154-156
A variety of thioacetals are deprotected to give their carbonyl compounds u
sing natural kaolinitic clay under microwave irradiation, avoiding the use
of toxic reagents and excess solvent.
