A comparativestudy of the homologation of representativeboronicesters with in situgenerated LiCH2X (X= Cl; Br; I) is presented wherein the reactivity differences arising out of the steric and electronic effects of the migrating groups, and the nature of the ester groups are determined and discussed.

With advances in organoboron chemistry, boron-centered functional groups have become increasingly attractive. In particular, alkylboron species are highly versatile reagents for organic synthesis, but the direct generation of alkyl radicals from commonly used, bench-stable boron species has not been thoroughly investigated. Herein, we describe a method for activating C–B bonds by nitrogen- or oxygen-radical
随着有机硼化学的进步,以硼为中心的官能团变得越来越有吸引力。特别是,烷基硼物质是用于有机合成的高度通用的试剂,但从常用的、实验室稳定的硼物质直接生成烷基自由基尚未得到彻底研究。在此,我们描述了一种通过氮或氧自由基转移激活 C-B 键的方法,该方法适用于烷基硼酸和酯,并且可用于 Michael 加成反应和 Minisci 反应以生成烷基或芳基化产物。
