Oxidation by Singlet Oxygen of 4,7-Dimethoxy-2,9-di-t-butyloxepinobenzofuran, an Oxidation Product of the Antioxidant BHA

Tetraphenylporphin-sensitized photo-oxidation of 4,7-dimethoxy-2,9-di-t-buthyloxepinobenzofuran (3) and reaction of the products with methanol cleaves the oxepine ring, producing the acetal (9) and its isomer (13), which may be derived respectively from the 1,4-endoperoxide and 1,2-dioxetane oxygen adducts of (3).The geometrical isomerization of (9) to (14), and the acid-catalysed hydrolysis of (9), (13) and (14) to the dihydrofuranylidenebenzofuranone (18) are described.Crystal structures were determined for compounds (9), (14), and (18).
