Abstract:
[figure: see text] A biphasic protocol for the catalytic olefin epoxidation with Mimoun-type complexes [MoO(O2)2(OPR3)] (1) was recently patented by BASF. Density-functional calculations have been carried out to identify potentially active species in addition to the parent complex 1. It has been found that the (mu 2,eta 1:eta 2-O2)-bridged dimer [MoO(O2)2(OPR3)]2 is significantly less reactive than the monomer. The calculations show that the parent complex is strongly activated by protons coordinating with the peroxo functionalities.

Preparation of Epoxides
Epoxides result from alkene oxidation, which can be achieved by a) air, b) peroxy acids, c) hypochlorous acids, and d) halohydrin cyclization.
Epoxidation with Peroxy Acids
Epoxidation of alkenes via oxidation with peroxy acids involves the conversion of a carbon–carbon double bond to an epoxide using the oxidizing agent meta-chloroperoxybenzoic acid, commonly known as MCPBA. Since the O–O bond of peroxy acids is very weak, the addition of electrophilic oxygen of peroxy acids to...
