Abstract

Provided are a 1-halo-6,9-pentadecadiene useful as an intermediate having a skipped diene skeleton and a method for producing (7Z,10Z)-7,10-hexadecadienal. More specifically, provided are a method for producing (7Z,10Z)-7,10-hexadecadienal including steps of subjecting a Grignard reagent formed from a (6Z,9Z)-1-halo-6,9-pentadecadiene to a nucleophilic substitution reaction with an orthoformate ester to obtain a (7Z,10Z)-1,1-dialkoxy-7,1 0-hexadecadiene; and hydrolyzing the (7Z,10Z)-1,1 - dialkoxy-7,10-hexadecadiene in the absence of an oxidation reaction to obtain the (7Z,10Z)-7,10-hexadecadienal; and the like.
