A RuII photocatalytic method was developed for the direct mono-benzoyloxylation of electron-rich aromatic and heteroaromatic systems even with an excess amount of benzoyl peroxide. The reaction was conducted at room temperature under visible light. The direct ArC–H benzoyloxylations occur without the assistance of any directing groups and can also tolerate various functional groups that have already
开发了一种 RuII 光催化方法,即使在过氧化苯甲酰过量的情况下,也可以直接将富电子芳香族和杂芳香族体系单苯甲酰氧基化。反应在室温下可见光下进行。直接的 ArC-H 苯甲酰氧基化无需任何导向基团的帮助,并且还可以耐受已经在过渡金属催化中表现出不同反应性的各种官能团。
