✦ Synopsis

The epoxidation of chalcone using hydrogen peroxide in the presence of a base in a two-phase medium system following the socalled Inverse Phase Transfer Catalysis (IPTC) process was investigated. Careful examination of various parameters including surfactant concentration, pH, H202 decomposition side-reactions and epoxide ring-opening, allowed us to determine optimal experimental conditions
