Method for synthesis of (Z5,E7)-dodecadien-1-ol, as a sex pheromone of the pine tree pine lappet moth (Dendrolimus pini) pest

摘要

object notification covers way synthesis (z5, e7) - dodekadien - 1 - olga model 1 as a sexual pheromone pest of pine barczatki sosnówki (dendrolimus pini).this method is characterized by the fact that leads to him,that: one part of molar (z) - 1 - jodo - 1-hexene - 6 - ola is subjected to reaction with excess of (e) - 1 - trimetylocyno - 1 - hexene using complex diacetonitrylopalladu dichloride (ii) as a catalyst.the fluorinated tris (pentafluorophenyl) triphenylphosphine, favourably fosfiny or tris (4 - trifluorometylofenylo) fosfiny, as a stabiliser in a mole ratio of ligandu to palladium of from 1.5 to 2.5, and an additional stabilizer in the form of copper chloride (i), added in quantities equal molar quantities ligandu fosfinowego,while this reaction is in the range of temperature 15 - 30 oc to total przereagowania jodoalkoholu,then releases and clearing the final product through a columnar single chromatography using silica gel as adsorbenta, recovering at the same time to 70% ligandu fosfinowego,with this process requires the use of only the initially dried solvent without stringent conditions of water free and anaerobic.
