practical protocol to prepare epoxides has been
established by using air as the oxidant in the presence of K2CO3 in isopropylbenzene (CM) at 80–140 °C.
The olefins are successfully converted into their corresponding epoxides
in yields of up to 99%. CM and K2CO3 are reused
in the scale-up recycling experiments. A reaction mechanism dominated
by the radical pathway is proposed according to the control experiments
and kinetic analysis.
