A cobalt-catalyzed asymmetric remote borylation of alkyl bromides is reported. The application of this migratory borylation was extended to other alkyl electrophiles (alkyl-X with X=I, Cl, OTs) and aryl halides. Additionally, a gram-scale reaction could be conducted while further transformation of the borylated products was demonstrated. Preliminary mechanistic studies indicated a radical reaction pathway may be involved.

钴催化烷基卤化物的不对称远程硼化

报道了钴催化的烷基溴的不对称远程硼基化。这种迁移硼基化的应用已扩展到其他烷基亲电子试剂（X=I、Cl、OTs 的烷基-X）和芳基卤化物。此外，可以进行克级反应，同时证明硼化产物的进一步转化。初步机理研究表明可能涉及自由基反应途径。
