Non-porphyrin catalysts for epoxidation

Epoxidation of ethylene by dioxygen takes place on heterogeneous silver catalysts at elevated temparatures [99-101]. There is one unconfirmed claim that a homogeneous reaction can be carried out [102]. 

Numerous attempts have been made at finding effective catalysts for homogeneous catalytic epoxidation under mild conditions with 0, but 

A liquid phase heterogeneous propylene epoxidation process has been described, using 13X Linde zeolite impregnated with ammonium 

Olefinic alcohol acetates, e.g. geranyl acetate are epoxidized with 

Cyclohexene is converted to cyclohexene oxide with 7 - 62 % selectivity in the presence of catalysts consisting of a mixture of two metal complexes, e.g. RhCl(PPh ) + Mo0(02)2HMPT(H20) [109]. The Rh
