Transfer hydrogenation reactions are of great interest to reduce diverse molecules under mild reaction conditions. To date, this type of reaction has only been successfully applied to alkenes, alkynes and polarized unsaturated compounds such as ketones, imines, pyridines, etc. The reduction of benzene derivatives by transfer hydrogenation has never been described, which is likely due to the high energy
转移氢化反应对于在温和的反应条件下还原各种分子非常重要。迄今为止,这种类型的反应仅成功地用于烯烃,炔烃和极化的不饱和化合物,例如酮,亚胺,吡啶等。从未描述过通过转移氢化还原苯衍生物的方法,这很可能是由于高使这些化合物脱芳香化所需的能量屏障。在此背景下,我们开发了一种催化转移氢化反应,用于还原苯衍生物和杂芳烃,从而在不需要压缩氢气的情况下,在室温下形成带有各种官能团的复杂三维支架。
