## Abstract Perchloric acid adsorbed on silica gel (HClO~4~/SiO~2~) has been found to be a highly efficient and versatile catalyst for the Michael addition of thiols to a wide variety of conjugated alkenes such as Ξ±,β‐unsaturated ketones, carboxylic esters, nitriles, amides and chalcones in dichlor
