  Cyanoborohydrides are efficient reagents in the reductive addition reactions of alkyl iodides and electron-deficient olefins. In contrast to using tin reagents, the reaction took place chemoselectively at the carbon–iodine bond but not at the carbon–bromine or carbon–chlorine bond. The reaction system was successfully applied to three-component reactions, including radical carbonylation. The rate constant

  氰基硼氢化物是烷基碘化物和缺电子烯烃的还原加成反应中的有效试剂。与使用锡试剂相反，该反应在碳碘键上发生化学选择，而在碳溴或碳氯键上没有发生。该反应体系已成功应用于三组分反应，包括自由基羰基化。通过动力学竞争法，在25°C下从氰基硼氢化四丁基铵中伯烷基脱氢的速率常数估计为<1×10 4 M –1 s –1。该值比氢化三丁基锡的值小3个数量级。

  Tin-free Giese reaction and the related radical carbonylation process proceeded efficiently in the presence of sodium cyanoborohydride and tetrabutylammonium cyanoborohydride. The reaction took place chemoselectively at the carbon-iodine bond but not at the carbon-bromine and carbon-chlorine bonds. The iodine atom transfer followed by hydride reduction of the resulting carbon-iodine bond is proposed

  在氰基硼氢化钠和氰基硼氢化四丁基铵的存在下，无锡Giese反应和相关的自由基羰基化过程得以有效进行。该反应在碳-碘键上发生化学选择，而在碳-溴和碳-氯键上没有发生。建议将碘原子转移，然后将所得的碳-碘键进行氢化还原，以作为可能的机理。

  Primary, secondary, and tertiary alkyl radicals formed by the photocatalyzed oxidation of organosilicates underwent efficient carbonylation with carbon monoxide (CO) to give a variety of unsymmetrical ketones. This study introduces the possibility of radical carbonylation under a photooxidative regime.

  This work concerns the Mg(OMe)2 promoted allylic isomerization of γ-hydroxy-α,β-alkenoic esters with TMEDA as an additive. The isomerization proceeded under mild conditions and afforded γ-keto esters in high yield (up to 96%) within 2 h. Both (Z)- and (E)-γ-hydroxy-α,β-alkenoic esters were tolerated under the reaction conditions. This transformation involves the in situ formation of a dienolate intermediate

  这项工作涉及以TMEDA作为添加剂的Mg（OMe）2促进的γ-羟基-α，β-链烯酸酯的烯丙基异构化。异构化在温和的条件下进行，并在2小时内以高收率（高达96％）提供了γ-酮酯。在反应条件下，（Z）-和（E）-γ-羟基-α，β-链烯酸酯均被耐受。该转化涉及从容易获得的γ-羟基-α，β-链烯酸酯原位形成二烯酸酯中间体。该原位生成的二烯醇酯可以与苯甲醛反应并经历一种实用，有用的串联烯丙基异构化-羟醛反应，得到更多官能的化合物。
