palladium‐catalyzed borylation of C(sp3)H bonds. Primary β‐C(sp3)H bonds in carboxylic acid derivatives as well as secondary C(sp3)H bonds in a variety of carbocyclic rings, including cyclopropanes, cyclobutanes, cyclopentanes, cyclohexanes, and cycloheptanes, can thus be borylated. This directed borylation method complements existing iridium(I)‐ and rhodium(I)‐catalyzed CH borylation reactions in terms
甲喹啉配体的基于有效地促进C的钯-催化的硼化(SP 3) H键。因此,可以使羧酸衍生物中的伯B-C(sp 3)H键以及各种碳环中的仲C(sp 3)pent H键(包括环丙烷,环丁烷,环戊烷,环己烷和环庚烷)进行硼化。此定向硼化方法补充了现有铱(I) -和铑(I) -催化Ç ħ硼化反应中的范围和操作条件方面。
