纳米钯/四丁基氟化铵体系催化合成对甲基肉桂酸丁酯的研究

Study on the Synthesis of Butyl 3-p-tolylacrylate with Nano-Pd/TBAF System as Catalyst

氯化钯在三水合四丁基氟化铵(TBAF·3H2O)中当场生成纳米钯,对碘甲苯与丙烯酸丁酯在纳米钯/四丁基氟化铵体系的催化下,选择性合成对甲基肉桂酸丁酯,反应收率高、后处理简单且催化体系可以回收重复使用,产物结构经由NMR和MS确证.

Pd nanoparticles were generated in situ from PdCl2 in tetrabutylammonium fluoride（TBAF·3H2O）.Butyl 3-p-tolylacrylate was synthesized by the reaction of 1-iodo-4-methylbenzene and butyl acrylate in the presence of nano-pd /TBAF as catalyst.The reaction was readily performed with good yield under mild conditions.Moreover,the catalytic system could be recovered and reused several times in the reaction.The structure of the product was characterized with NMR and MS spectra.
