A palladium‐catalyzed three‐component reaction between fluoroalkyl bromides, arylboronic acids, and alkenyl aldehydes has been developed and provides facile access to 5‐, 6‐, or 7‐difluoroalkylated ketones under very mild reaction conditions. The resultant products can be smoothly converted into CF2‐containing tetrahydronaphthalenes by a novel silver‐catalyzed intramolecular decarboxylative cyclization
已经开发出了氟烷基溴化物,芳基硼酸和烯基醛之间的钯催化三组分反应,该反应可在非常温和的反应条件下轻松获得5,6或7二氟烷基化的酮。通过新的银催化的5-芳基-2,2-二氟戊酸的分子内脱羧环化反应,可以将所得产物平稳地转化为含CF 2的四氢萘。
