We demonstrate how FlowNMR spectroscopy can readily be applied to investigate photochemical reactions that require sustained input of light and air to yield mechanistic insight under realistic conditions. The Eosin Y mediated photo-oxidation of N-allylbenzylamine is shown to produce imines as primary reaction products from which undesired aldehydes form after longer reaction times. Facile variation of reaction conditions during the reaction in flow allows for probe experiments that give information about the mode of action of the photocatalyst.

实时高分辨率FlowNMR光谱在线监测光催化反应

我们演示了如何将FlowNMR光谱技术轻松地用于研究光化学反应，这些光化学反应需要持续输入光和空气才能在现实条件下产生机械的见解。曙红Y介导的N-烯丙基苄胺的光氧化反应产生亚胺作为主要反应产物，在较长的反应时间后，会形成不需要的醛。流动反应过程中反应条件的容易变化允许进行探针实验，以提供有关光催化剂作用方式的信息。
