Efficient Heterogeneous Epoxidatlon of Alkenes by a Supported Tungsten Oxide Catalyst...

摘要

Epoxides are important chemical intermediates in the laboratory as well as the chemical industry. Catalytic epoxidation of alkenes with H2O2 has attracted much attention because of the sustainable nature of the reaction, for example, the use of catalysts, the high content of active oxygen species in H2O2, and the formation of water as the sole by-product. A number of efficient methods for the epoxidation of alkenes with transition-metal catalysts, such as Ti, V, Mn, Fe, W, Re, Pt, have been reported.
