The first copper-catalyzed regiodivergent cyanoboration of internal allenes with B2pin2 and NCTS derivatives has been developed. MeOH was identified as the necessary additive for the regeneration of LCu-Bpin species. Computational studies revealed that the copper-mediated allylic cyanation is the regio- and stereo-determining step, while the MeOH-assisted transmetalation with B2pin2 is the rate-determining
已经开发出第一个铜催化的具有 B 2引脚2和 NCTS 衍生物的内部丙二烯区域发散氰基硼化反应。MeOH 被确定为 LCu-Bpin 物种再生的必要添加剂。计算研究表明,铜介导的烯丙基氰化作用是区域和立体决定步骤,而甲醇辅助的 B 2 pin 2金属转移是速率决定步骤。
