CF3-containing esters smoothly reacted with electron-deficient alkenes in the presence of a phosphine (2-dicyclohexylphosphino-2′,4′,6′-triisopropylbiphenyl) organocatalyst at room temperature in an aerobic atmosphere. These Michael reactions efficiently provided products with a CF3 quaternary carbon center.
在膦(2-二环己基膦基-2',4',6'-三异丙基联苯)有机催化剂的存在下,在需氧气氛下,含CF 3的酯与缺电子的烯烃平稳地反应。这些迈克尔反应有效地为产物提供了CF 3季碳中心。
