Abstract: The effect of promoters EuCl3, LaCl3, CeCl3 and PrCl3 on the yields of the chemoselective esterifiction of vanillyl alcohol was studied. The results showed that when the molar ratio of vanillyl alcohol/ LaCl3(1:0.005), yields of vanillyl caprylate, vanillyl deaconate and vanillyl dilaurate were as follow 87 percent, 85 percent and 71 percent.

Key words: Capsinoids, vanillyl alcohol, lanthanide salts, synthesis
