Abstract

In our study, a method for the epoxidation of cis-cyclooctene was researched using a series of Lindqvist type POMs Cp*2MoxW6−xO17 (x=0, 2, 4, 6) and [Cp*MoxW6−xO18]− (x=0, 1, 5, 6) as a catalyst in the presence of 30 % H2O2 as a green oxidant. This catalytic system containing polyoxometalates and H2O2 has applied the most succesful system in obtaining epoxide product with excellent yields for cis-cyclooctene in acetonitrile at 55 °C. Maximum epoxidation efficiency of 99 % was observed under optimized conditions for Ph4P[Cp*MoW5O18] (2c).
