Pd-catalyzed difluoromethylation of di-, tri- or tetra-substituted vinyl bromides, triflates, tosylates and nonaflates under mild conditions is described. The reaction tolerates a wide range of functional groups, such as bromide, chloride, fluoride, ester, amine, nitrile, and protected carbonyl, thus providing a general route for the preparation of difluoromethylated alkenes.
描述了在温和条件下钯催化二取代、三取代或四取代的乙烯基溴化物、三氟甲磺酸酯、对甲苯磺酸酯和九氟丁磺酸酯的二氟甲基化反应。该反应能耐受多种官能团，如溴、氯、氟、酯、胺、腈和保护的羰基，从而为制备二氟甲基化烯烃提供了一条通用途径。
