Abstract
The reactivity of sterically hindered phenols toward free radicals of the h ydrocarbon cumene was studied. New compounds, i.e. methyl cis-13(12)-(3-(3, 5-di-tert-butyl-4-hydroxyphenyl)propionyloxy)-12(13)-hydroxyoleate and cis- 13(12)-(3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionyloxy)-12(13)-hydroxyol eic acid were synthesized starting from vernolic acid and its methyl ester, respectively, and 3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionic acid. Bot h new compounds possess antioxidant activities similar to those of commerci ally available antioxidants.
