Unsensitized photo-oxidation of the furan (1) yields acrylate (4) as the major product.This reaction and that with singlet oxygen proceed through completely independent routes.Oxidation of (1) by triplet oxygen has also been studied using AIBN as a free-radical initiator; in addition to (4) the product (12), incorporating the isobutyronitrile radicals, was formed.

A comparison of the ehaviour of endo-peroxides of the β-furoic esters (1a, b and d-f) and of the furans (1c or g), with the same 2,5-substituents, shows that the thermal instability of these compounds is related to the electron density in the bicyclic unsaturated ring.This also accounts for the higher stability of the alkyl-substituted endo-peroxides (1a-c) as compared with that of the aryl-substituted derivatives (1d-g), as well as for the different course of the thermal conversion in the two series.
Photosensitized Oxidation of Furans. III. Comparison Between Photochemically and Thermally Generated Singlet Oxygen Oxidation of 3-Methoxycarbonyl-2-methyl-5-phenylfuran

Thermal conversion of furan endo-peroxide I, obtained by photosensitized oxidation of furan II, yields very similar results to those of the oxidation of the furan II by thermally generated singlet oxygen, showing that also in the latter case the endo-peroxide I is the key intermediate.A mechanistic interpretation of the furan II-singlet oxygen reaction is reported.
