I am aware the potential of ultrasound to increase the reaction rate; in a report by Marcel et al. "Ultrasound-assisted epoxidation reaction of long-chain unsaturated fatty esters" are detailed few examples in which MCPBA oxidize alkenes to epoxides under ultrasonic energy.
Normally this reaction would go through a concerted epoxidation mechanism and in aqueous medium would generate a diol (most of the time, it al depends by the stability of the epoxide).
----I am wondering if the use of ultrasound for the same reaction (in aqueous medium 20%) would influence the reaction mechanism through thermal dissociation of the peroxyacid forming MCB* and OH*??? [* = radical]
or the ultrasonic energy would just work as "catalyst" during the concerted epoxidation mechanism.
Working at low frequency of 21kHz for 5-15 min.
Please feel free to comment and provide suggestions.
Thanks
