Abstract

Michael addition of thiophenol to chalcone was studied in different solvents. It was proved that reaction proceed very well in ionic liquids and chosen conventional solvents without any catalyst. It was also proved that reaction proceed well also with other thiols and other enones. Addition of selenophenol to chalcone in ethanol was also successful.
