The enantioselective fluorination of readily available cyclic allylic chlorides with AgF has been accomplished using a Pd(0) catalyst and Trost bisphosphine ligand. The reactions proceed with unprecedented ease of operation for Pd-mediated nucleophilic fluorination, allowing access to highly enantioenriched cyclic allylic fluorides that bear diverse functional groups. Evidence that supports a mechanism
已经使用 Pd(0) 催化剂和 Trost 双膦配体完成了容易获得的环状烯丙基氯化物与 AgF 的对映选择性氟化。该反应以 Pd 介导的亲核氟化前所未有的简便操作进行,允许获得具有不同官能团的高度对映体富集的环状烯丙基氟化物。提供了支持通过 S(N)2 型氟化物攻击 Pd(II)-烯丙基中间体而形成 CF 键的机制的证据。
