Abstract

PURPOSE: To obtain a cis-olefin derivative a sex attractant substance readily, by reacting an easily obtainable cis-alkenyl copper compound with 3-oxo-1-butene, etc. as raw material compounds.
CONSTITUTION: A cis-alkenyl copper compound shown by the formula I (R is alkyl or alkenyl; L is ligand) is reacted with a compound (e.g., 3-oxo-1-hexene, 3-oxo-1- octene, etc.) shown by the formula II (R' is the same as R; X is H, halogen, halogenoid; Y is ethylene or vinyene) preferably in the presence of an organic phosphorus compound, to give a compound shown by the formula III. The compound shown by the formula I is obtained by reacting a copper halide with an alkyl or alkenyl magnesium halide, followed by bubbling an acetlylene gas. The compound shown by the formula II is obtained by reacting an alkyl or alkenyl magnesium halide with acrolein, followed by oxidation.
