Transformation of oxazolidinones to corresponding oxazolidine-2,4-diones is enabled by mpg-CN, a carbon nitride photocatalyst, using oxygen gas as an oxidant. The reaction proceeds via proton-coupled electron transfer. The mechanism of this transformation is established by photocatalytic experiments, transient absorption spectroscopy and DFT calculations.
mpg-CN(一种氮化碳光催化剂)使用氧气作为氧化剂,可以将恶唑烷酮转化为相应的恶唑烷-2,4-二酮。反应通过质子耦合电子转移进行。这种转变的机制是通过光催化实验、瞬态吸收光谱和 DFT 计算建立的。
