Oxidation is a major chemical process to produce oxygenated chemicals in both nature and chemical industry. Currently, industrial deep oxidation processes from polyalkyl benzene are major routes to produce benzoic acids and benzene polycarboxylic acids (BPCAs), while to some extent suffering from the energy-intensive and potentially hazardous drawbacks and the sluggish separation issues. In this report, visible-light-induced deep aerobic oxidation of (poly)alkyl benzene to benzene (poly)carboxylic acids was developed. CeCl3 was proved to be an efficient HAT (Hydrogen Atom Transfer)catalyst in the presence of alcohol as both hydrogen and electron shuttle. Dioxygen (O2) was found as a sole terminal oxidant. In most cases, pure products were easily isolated by simple filtration, showing the advantages of for scaling up. The reaction provides an ideal way to form valuable fine chemicals from abundant petroleum feedstocks.

可见光诱导的烷基芳烃深度有氧氧化

氧化是自然界和化学工业中生产含氧化合物的主要化学过程。目前，由聚烷基苯进行的工业深度氧化工艺是生产苯甲酸和苯多羧酸（BPCA）的主要途径，同时在一定程度上遭受了能源密集型和潜在危险的缺点以及缓慢的分离问题的困扰。在该报告中，开发了可见光诱导的（聚）烷基苯深度好氧氧化为苯（聚）羧酸的方法。事实证明，CeCl3在氢和电子穿梭的醇存在下是一种有效的HAT（氢原子转移）催化剂。发现双氧（O2）是唯一的终端氧化剂。在大多数情况下，通过简单的过滤就可以很容易地分离出纯净的产品，这显示出扩大规模的优势。
