A nickel-catalyzed, enantioselective, three-component fluoroalkylarylation of unactivated alkenes with aryl halides and perfluoroalkyl iodides has been described. This cross-electrophile coupling protocol utilizes a chiral nickel/BiOx system as well as a pendant chelating group to facilitate the challenging three-component, asymmetric difunctionalization of unactivated alkenes, providing direct access
镍催化、对映选择性、三组分氟烷基芳基化未活化的烯烃与芳基卤化物和全氟烷基碘化物已被描述。这种交叉亲电偶联方案利用手性镍/BiOx 系统以及悬垂的螯合基团来促进未活化烯烃的具有挑战性的三组分不对称双官能化,从而以高效和出色的对映选择性直接获得有价值的手性 β-氟烷基芳基烷烃. 温和的条件允许广泛的底物范围以及良好的官能团耐受性。
