Experimental evidence for multiple oxidation pathways in the (salen)Mn-catalyzed epoxidation of alkenes

The substrate electronic effects on the selectivity in the catalytic epoxidation of para-substituted cis stilbenes 2a-i were investigated by using (R,R)-[N,N′-bis(3,5-di-tBu-salicylidene)-1,2-cyclohexanediamine] manganese(III) chloride 1 in benzene as the catalyst with iodosobenzene as the terminal oxidant. A Hammett study of the selectivity results reveals a stronger electrophilic character than previously assumed in the (salen)Mn-catalyzed reaction. In general, the best correlations with the experimental values were obtained by using the Hammett σ+ values, which gave ρ = -1.37 for the rate of cisepoxide formation and ρ = -0.43 for the rate of the stepwise process leading to the corresponding trans product. The reaction involves two separate pathways as indicated also by the competitive breakdown of the intermediate on the path to trans epoxide for methoxy-substituted substrates. The asynchronicity in the concerted pathway leading to cis epoxide is apparent for 4-methoxy-4′-nitrostilbene, which yields cis epoxide with 75% ee entirely as a result of electronic effects.

Irradiation of trans-stilbene oxide with naphthalene-1,4-dicarbonitrile as sensitiser in the presence of electron deficient dipolarophiles leads, via a presumed carbonyl ylide, to various dihydro- and tetrahydro-furans.This chemistry is extended, for the

Oxidation of Alkenes and Sulphoxides with a Mixture of Potassium Superoxide and Diethyl Chlorophosphate

The reaction of potassium superoxide with diethyl chlorophosphate in the presence of 18-crown-6 ether gave at least two oxidizing agents, one of which was electrophilic and used in the oxidation of alkenes, whilst the other, nucleophilic in type, was important in the oxidation of sulphoxides.
