  equipment. In this report, photo-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, implying

  氧化是自然界和化学工业中生产含氧化学品的主要化学过程。目前，苯甲酸和苯多羧酸（BPCAs）的工业生产主要以聚烷基苯的深度氧化为主，由于形成消耗臭氧层的溴化溴和对生产设备的腐蚀危害，在环境和经济上都有些不利。 . 在这份报告中，开发了（多）烷基苯的光诱导深度有氧氧化为苯（多）羧酸。CeCl 3被证明是在醇存在下作为氢和电子穿梭的有效HAT（氢原子转移）催化剂。双氧 (O 2) 被发现是唯一的终端氧化剂。在大多数情况下，纯产品很容易通过简单的过滤分离，这意味着大规模实施的优势。该反应提供了从天然丰富的石油原料中生产有价值的精细化学品的理想方案。
