• Preparation of Functionalized Diaryl- and Diheteroaryllanthanum Reagents by Fast Halogen-Lanthanum Exchange
  作者：Andreas D. Benischke、Lucile Anthore-Dalion、Guillaume Berionni、Paul Knochel

  DOI：10.1002/anie.201709553

  日期：2017.12.18

  Aryl and heteroaryl halides (X=Br, I) undergo a fast and convenient halogen–lanthanum exchange with nBu2LaMe, which leads to functionalized diaryl‐ and diheteroaryllanthanum derivatives. Subsequent trapping reactions with selected electrophiles, such as ketones, aldehydes, or amides, proceeded smoothly at −50 °C in THF, affording polyfunctionalized alcohols and carbonyl derivatives. Kinetic competition

  芳基和杂芳基卤化物（X = Br，I）与nBu 2 LaMe进行快速便捷的卤素-镧交换，这导致官能化的二芳基和二杂芳基镧衍生物。随后与选定的亲电子试剂（如酮，醛或酰胺）的捕集反应在-50°C的THF中顺利进行，得到多官能化的醇和羰基衍生物。动力学竞争实验显示出与Br / Mg交换相似的反应趋势，但速率提高了10 6倍，使其与Br / Li交换相当。
• MgCl2-Accelerated Addition of Functionalized Organozinc Reagents to Aldehydes, Ketones, and Carbon Dioxide

  Pump it up! The sluggish reactivity of organozinc reagents in additions to aldehydes, ketones, and CO2 can be increased by MgCl2, which is usually generated in the preparation of the zinc reagent. The direct reaction with CO2, in particular, opens an expeditious route to phenylacetic acid derivatives, as demonstrated in a short synthesis of ibuprofen (see scheme).

  加油！MgCl 2可以增加除醛，酮和CO 2之外的有机锌试剂的反应迟钝，这通常是在锌试剂的制备过程中产生的。特别是与CO 2的直接反应为苯乙酸衍生物的开发开辟了一条捷径，如布洛芬的短暂合成所证明的（见方案）。
