Abstract

AbstractChlorophyll‐sensitized peroxidation of methyl laurate and methyl stearate was carried out at 30–40 C under intermittent exposure to light from a 500 w tungsten bulb. Hydroperoxides were isolated by solvent partition, reduced to hydroxy esters and purified by silicic acid column chromatography and preparative thin layer chromatography (TLC). Gas liquid chromatography, TLC, IR spectrophotometry, NMR and mass spectroscopy of the hydroxy esters showed that the oxygen attack was exclusively on the α‐methylenic carbon atom.
