Reactions proceeding through open-shell, single-electron pathways offer attractive alternative outcomes to those proceeding through closed-shell, two-electron mechanisms. In this context, samarium diiodide (SmI(2)) has emerged as one of the most important and convenient-to-use electron-transfer reagents available in the laboratory. Recently, significant progress has been made in the reductive chemistry of other divalent lanthanides which for many years had been considered too reactive to be of value to synthetic chemists. Herein, we illustrate how new samarium(II) complexes and nonclassical lanthanide(II) reagents are changing the landscape of modern reductive chemistry.
通过开壳层、单电子途径进行的反应为通过闭壳层、双电子机制进行的反应提供了有吸引力的替代结果。在这种情况下，二碘化钐 (SmI(2)) 已成为实验室中可用的最重要和最方便的电子转移试剂之一。最近，其他二价镧系元素的还原化学取得了重大进展，多年来，这些元素被认为反应性过高，对合成化学家没有价值。本文中，我们展示了新的钐(II)配合物和非经典镧系元素(II)试剂如何改变现代还原化学的格局。
