Abstract

Tri-Et amine liganded vinyl cuprate was employed in the synthesis of the major components of the sex pheromone of old world bollworm moth (Heliothis armigera), cis-7-hexadecenal (I) and cis-11-hexadecenal (II), and gypsy moth (Porthetria dispar), 7,8-epoxy-2-methyloctadecane (III), with high Z purity (99.9%). The overall yields of I and II from octyllithium and BuLi were 70% in 3 steps, and that of III from decyllithium was 60% in 2 steps.

Key words: TRIETHYL AMINE P, C16 COMPOUNDS, ETHYLENE, COPPER, CARBENE, EPOXIDE, ALDEHYDES, INSECT HORMONE, SEX PHEROMONE, C18 COMPOUNDS
