A novel method for catalytic remote bismetalation of alkene substrates by the addition of dimetal reagents is accomplished by using chain walking. In the presence of a palladium catalyst, the reaction of various 1,n-dienes and diborons were converted into cyclopentane derivatives with two boryl groups at remote positions via facile regioselective transformation of an unactivated sp³ C–H bond to a C–B bond. Sequential construction of three distant bonds, which is difficult to achieve by any method, was accomplished for the reactions of 1,n-dienes (n ≥ 7).

链行走钯催化二烯与二硼的远程二硼环化

一种通过添加二金属试剂催化烯烃底物远程双金属化的新方法是通过使用链行走实现的。在钯催化剂的存在下，通过将未活化的 sp ³ C-H 键区域选择性转化为 C-B 键，各种 1， n-二烯和二硼的反应被转化为在远端位置具有两个硼基的环戊烷衍生物. 1, n-二烯(n≥7 )的反应实现了任何方法都难以实现的三个远距离键的顺序构建。
