Carbene transfer reactions play an important role in the field of organic synthesis because of their ability to construct a variety of molecules. Herein, we reported on blue light-induced cyclopropenizations of N-tosylhydrazones in water, which avoids the use of expensive metal-based catalysts and toxic organic solvents. This metal-free and operationally simple methodology enable highly efficient cyclopropenizations
碳转移反应由于其能够构建多种分子的能力而在有机合成领域中起着重要作用。在本文中,我们报道了N-甲苯磺酰blue在水中的蓝光诱导环丙烷化反应,从而避免了使用昂贵的金属基催化剂和有毒有机溶剂。这种无金属且操作简单的方法可在温和的反应条件下实现高效的环丙烷化,XH插入反应和环丙烷化。
