A new family of stereoconvergent cross-couplings of unactivated secondary alkyl electrophiles has been developed, specifically, arylamine-directed alkyl-alkyl Suzuki reactions. This represents the first such investigation to be focused on the use of alkyl chlorides as substrates. Structure-enantioselectivity studies are consistent with the nitrogen, not the aromatic ring, serving as the primary site
已开发出一类新的未活化仲烷基亲电试剂的立体会聚交叉偶联,特别是芳胺导向的烷基-烷基 Suzuki 反应。这是第一次集中于使用烷基氯作为底物的此类研究。结构对映选择性研究与作为芳胺与催化剂配位的主要位点的氮而不是芳环一致。这种不对称交叉偶联的速率定律与作为催化循环的周转限制步骤的金属转移相兼容。
