Reaction of thiophenol with ethylene carbonate in the presence of the Na-X zeolite catalyst gave the highest yield of 2-(phenylthio)ethanol (100%), while reaction with propylene carbonate a highest yield of regioselective product 1-(phenylthio)propan-2-ol was obtained (97%). Enantiomerically pure 1,2-propylene carbonate gave highly regioselective and stereospecific phenylthiopropanol, demonstrating that original chirality of propylene carbonate is retained. A plausible mechanism has been proposed for zeolite-catalyzed transformation involving a chemoselective nucleophilic attack of thiophenoloxide ion onto the less-substituted carbon of cyclic carbonate. The Na-X zeolite catalyst is recyclable and provides advantages of green chemistry approach to the synthesis of beta-hydroxy sulfides without the use of any solvent.</p>10abeta-hydroxy sulfide10aethylene carbonate10apropylene carbonate10athiophenol10azeolite1 aUpare, Pravin, P.1 aKinage, Anil, K.1 aShingote, Savita, K.1 aGupte, Sunil, P.  uhttps://library.ncl.res.in/content/environmentally-benign-synthesis-beta-hydroxy-sulfides-using-cyclic-carbonates-catalyzed-0
