Solvent Free Protection of Carbonyl Group under Microwave Irradiation. -The conversion of carbonyl compounds (I) to the corresponding acetals/ketals (III) or dioxolanes (V) is readily achieved by neat KSF clay or PTSA-catalyzed microwave irradiation in the presence of orthoformates, 1,2-ethanediol,
A series of g-thionolactones was synthesized, with good yields, using a new combination of Lawesson's reagent (LR) and hexamethyldisiloxane (HMDO) in solvent-free conditions under microwave irradiation.
