SYNTHESIS OF A NOVEL UNSATURATED POLYOLEFIN INTERMEDIATES, ALDEHYDE AND FATTY ACID
Hussein Habeeb Mustafa*
Novel unsaturated compounds with the required skip-conjugated (Z,Z)-double bonds configuration are
synthesized through a coupling of aldehydes with phosphonium salt through a series of Wittig reactions as a
main step. The products were diagnosed by using NMR spectrum, infrared (IR) and mass spectrometer
techniques. It is concluded that these products could widely be used as a fatty acid and a useful intermediates
in the synthesis of pheromones instead of insecticides, and several chemical reactions.
Keywords: Wittig reaction, unsaturated fatty acid, skip-conjugated alkenes, pheromone.
