ABSTRACT
The catalytic epoxidation of olens constitutes an important research area and represents the core of a variety of chemical processes for producing bulk and ne chemicals. There are many name reactions for epoxidation, e.g., JacobsenKatsuki epoxidation, Prilezhaev reaction, Sharpless epoxidation, Shi epoxidation, etc., as well as other processes using various catalysts, oxygen sources, reaction media, and additives. The conventional processes for olen epoxidation are still the chlorohydrin process (a chlorine-using noncatalytic process) and catalytic processes where organic peroxides are used extensively. The disadvantages of these classical processes are quite obvious from the economic and environmental viewpoints.1
