摘要
Abstract In our study, a method for the epoxidation of cis ‐cyclooctene was researched using a series of Lindqvist type POMs Cp* 2 Mo x W 6−x O 17 (x=0, 2, 4, 6) and [Cp*Mo x W 6−x O 18 ] − (x=0, 1, 5, 6) as a catalyst in the presence of 30 % H 2 O 2 as a green oxidant. This catalytic system containing polyoxometalates and H 2 O 2 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 Ph 4 P[Cp*MoW 5 O 18 ] (2c).
