通过1,2-迁移过程可实现烯丙醇的电化学氧化双官能化,以合成β-三氟甲基酮。利用CF 3 SO 2 Na作为自由基源可以轻松获得一系列β-三氟甲基酮,而无需使用金属和牺牲性化学氧化剂。重要的是,该协议不仅实现了芳基迁移,而且还提供了烷基迁移产物。另外,电化学催化的环膨胀和克级反应证明了该方案的合成有用性。
Iron-catalyzedtrifluoromethylation with concomitant 1,2-migration of an aryl group starting from diaryl allyl alcohol was achieved under mild conditions. This reaction system affords alpha-substituted-beta-trifluoromethyl carbonyl compounds in high efficiency. In the case of substrates bearing different aryl groups, selective migration was observed.
