Methyl linoleate hydroperoxide produced by autoxidation was refluxed with 10(-4) M Cu-naphthenate in benzene. Two new geometrical isomers of oxooctadecadienoate (compounds I and II) were found in addition to the four known isomers. They were isolated by a Sephadex LH-20 column chromatography with chloroform-hexane (2:1) and purified by HPLC on Nucleosil ®100-5 and Zorbax ODS columns. UV, IR, MS, and
