The title compounds were synthesized starting from tosyl ether derivative of glycerol using KF/Al2O3 and
PEG-400 as solvent. The reactions were performed under mild conditions with a range of aliphatic and aromatic thiols and
the catalytic system was reused without previous treatment and with comparable activity for one additional reaction.
Keywords: Alumina, catalyst, glycerol, green chemistry, KF/Al2O3, PEG-400, potassium fluoride, protective group, renewable
feedstock, solid supported, sulfur compounds, thioethers, thiol, thiolate anion, tosylsolketal.
