A method is described as the simplest way for the synthesis of (Z)-9-tricosene, the sex pheromone of the housefly.The mixture of prodicts obtained on repeating the title syntheses appeared to be much more complex than described previously.The following by-products were identified using the GC/MS method: hydrocarbons with a straight chain - saturated C8 to C23, unsaturated C13 to C24; the dienes C20 and C21; and the methyl esters of fatty acids C7 to C22 (depending on the reaction path).In the products of the anodic coupling of erucic and propionic acids considerable amounts of high-molecular compounds were formed.The non-reported new compounds with molecular weights of 584 and 614 were formed in addition to the excepted 9,33-dotetracontadiene (m.w. 586).Their structures were elucidated by mass and ir spectroscopy as 9,20,33-dotetracontatriene (m.w. 584) and 9,34-tritetracontadien-21-one (m.w. 614).Mechanism of the formation of the by-products are proposed.
