A new and efficient nickel-catalyzed alkylation of CAr–O electrophiles with B-alkyl-9-BBNs is described. The transformation is characterized by its functional group tolerance and provides a practical and versatile access to various Csp2–Csp3 bonds through Csp2–O substitution, without the restriction of β-hydride elimination. Moreover, the advantage of the newly developed method was demonstrated in
描述了一种新的,高效的镍催化的C Ar –O亲电试剂与B-烷基-9-BBN的烷基化反应。该转变的特征在于其对官能团的耐受性,并通过C sp2- O取代为各种C sp2- C sp3键提供了实用而通用的访问途径,而没有消除β-氢化物的限制。此外,新开发方法的优势在选择性和顺序的C–O键激活过程中得到了证明。
