The hydroperoxide of methyl linoleate containing 95% 13-hydroperoxide and 5% 9-hydroperoxide was decomposed in benzene with 10-4M cupric naphthenate at 75-80°C under degassed conditions. The decomposition products were fractionated by Sephadex LH-20 column chromatography with chloroform-hexane (2:1, v/v) and the fractions were purified by HPLC. In addition to the known products, three compounds were identified as methyl 9-(2-(2, 5-dihydro-5-pentylfuryl))-nonanoate, methyl 8-(2-furyl)-octanoate, and methyl 9(13)-hydroperoxy-12, 13-(9, 10)-epoxy-10(12)-octadecenoate as miner decomposition products by MS and IR spectrophotometry.
