The reaction of aryl iodides or vinyl triflates with a variety of olefins in supercritical carbon dioxide (scCO2), in the presence of triethylamine and palladium on carbon, has been investigated. Methyl acrylate, styrene and acrylonitrile afford vinylic substitution products. Butenone reacts with aryl iodides to form a mixture of vinylic substitution and hydroarylation (formal conjugate addition) products. n-Butyl, vinyl ether gives rise to the formation of products arising from the α- and β-arylation process.
在三乙胺和碳载钯的存在下,研究了芳基碘或乙烯基三氟磺酸盐与多种烯烃在超临界二氧化碳(scCO₂)中的反应。甲基丙烯酸甲酯、苯乙烯和丙烯腈提供乙烯基取代产物。丁烯酮与芳基碘反应生成乙烯基取代和氢芳基化(形式共轭加成)产物的混合物。正丁基乙烯醚产生α-和β-芳基化过程的产物。
