Metathesis syntheses of pheromones or their components

The invention relates to lures of the metathesis reducing agent pheromone or a component, for example acetic acid E-5- decylene ester, peach resin resin gel eating of pheromone main component; (5R, 6S) - 6 - B Acid radical-five to 16 lactone (16) lactone, the air spawning lures agent, pheromoneE or 9, WHEREIN 11 to 16 carbon and olefine aldehydes (16 carbon-2 olefine aldehydes), Americas carya and sheath moth larva moth, pheromoneFormic acid - 9 tetradecene ester, plutella maculipennis (DBM) pheromone, analogueAcetic acid 11 to tetradecene ester, Omnivorous Leafroller (OLR); pheromoneAcetic acid E-4- tridecylene ester, pond bookworm moth (TPW) pheromone main component; E, E-8,10 to 12 carbon dienol, the bookworm (moth) of pheromone. The synthesis preferably in the I-IV a metathesis catalyst, mixture at least reaction step, the raw materials of the trade usual obtainable, having relatively short period process. The synthesis of the aerobic yield, does not need expensive or the top device. The invention claims a cross metathesis α - ω of the B acid group and an α - ω - dihalide, relates to a ω of the cheap method for synthesising halogenated enol, which is easy to transform The of the traditional the method according alkylogen alcohol is.
