Synthesis of a tsetse fly kairomone component (3-propylphenol), a detergent [sodium 2-(dec-8-enyl)-6-hydroxybenzenesulfonate], a polymer additive (1-octene), and a detergent precursor [3-(non-8-enyl)phenol] using cardanol [3-(pentadec-8-enyl)phenol], has been accomplished. Both carboncarbon double bond isomerization and metathesis methodologies were employed in the syntheses of these target molecules. The kairomone component was obtained, albeit in low yield, in three steps starting with cardanol. Synthesis of a new detergent, sodium 2-(dec-8-enyl)-6-hydroxybenzenesulfonate, was achieved by direct metathesis of cardanol with cis-2-butene followed by sulfonation and basification. Finally, synthesis of 1-octene and 3-(non-8-enyl)phenol was accomplished in one pot by direct metathesis of cardanol with ethylene. These products have been characterized spectroscopically, especially using 1H and 13C NMR.
