  reaction in the chemical industry. A large proportion of SM couplings employ dipolar aprotic solvents; however, current sustainability initiatives and increasingly stringent regulations advocate the use of alternatives that exhibit more desirable properties. Here we describe the scope and utility of the bio-derived solvent Cyrene™ in SM cross-couplings and evaluate its suitability as a reaction medium

  Suzuki-Miyaura (SM) 交叉偶联是化学工业中使用最广泛的 Pd 催化的 C-C 键形成反应。大部分 SM 偶联剂使用偶极非质子溶剂；然而，当前的可持续性举措和日益严格的法规提倡使用具有更理想特性的替代品。在这里，我们描述了生物衍生溶剂 Cyrene™ 在 SM 交叉偶联中的范围和效用，并评估其作为反应介质的适用性，以实现从发现到克级规模的这一基准转化。
• Tandem Chemoselective Suzuki–Miyaura Cross‐Coupling Enabled by Nucleophile Speciation Control
  作者：Ciaran P. Seath、James W. B. Fyfe、John J. Molloy、Allan J. B. Watson

  日期：2015.8.17

  Control of boronic acid speciation is presented as a strategy to achieve nucleophile chemoselectivity in the Suzuki–Miyaura reaction. Combined with simultaneous control of oxidative addition and transmetalation, this enables chemoselective formation of two CC bonds in a single operation, providing a method for the rapid preparation of highly functionalized carbogenic frameworks.

  控制硼酸的形成是实现铃木-宫浦反应中亲核试剂化学选择性的一种策略。与同时控制氧化加成和过渡金属化相结合，这使得能够在一次操作中化学选择性地形成两个CC键，从而为快速制备高度官能化的生碳骨架提供了一种方法。
