high catalyst loadings, as the processes are sluggish and complex equilibria are involved. Here, in situ light irradiation with a specific wavelength inside NMR is applied to increase reaction rates of hydrazone cyclization. This enhancement was achieved by isomerizing the substrate to the reactive configuration.
在有机催化中,许多转化需要相当高的催化剂负载量,因为过程缓慢且涉及复杂的平衡。在这里,在 NMR 内使用特定波长的原位光照射来提高腙环化的反应速率。这种增强是通过将底物异构化为反应性构型来实现的。
