在可见光驱动的基于单电子转移的有机转化中，伊红Y是一种众所周知的经济的金属催化剂替代品，可以作为C-H活化的有效的直接氢原子转移催化剂。以C-H键与缺电子烯烃的烷基化为模型研究揭示了一个极其广泛的底物范围，可以很容易地获得各种重要的合成子。这种基于伊红的光催化氢原子转移策略有望以绿色和可持续的方式实现广泛的天然C-H键的多样化功能化。
Eosin Y, a well-known economical alternative to metal catalysts in visible-light-driven single-electron transfer-based organic transformations, can behave as an effective direct hydrogen-atom transfer catalyst for C-H activation. Using the alkylation of C-H bonds with electron-deficient alkenes as a model study revealed an extremely broad substrate scope, enabling easy access to a variety of important synthons. This eosinY-based photocatalytic hydrogen-atom transfer strategy is promising for diverse functionalization of a wide range of native C-H bonds in a green and sustainable manner.
