制备方法与用途

化学性质
5-乙酰基噻吩-2-羧酸是一种浅黄色的结晶体，具有良好的热稳定性和化学稳定性，并能溶解于多种有机溶剂，如乙醇、乙醚和氯仿等。

生产方法
在氧(O₂)气氛下，将噻吩衍生物(0.1 mmol, 0.0140 g)、CeCl₃（5 mol%，0.0012 g）、CCl₃CH₂OH (1.0当量, 0.0149 g) 和 CH₃CN (2 mL) 加入反应管中。将混合物垂直放置于400 nm LED灯(10W) 下，然后在30°C的蓝光照射下搅拌24小时。通过薄层色谱(TLC)指示反应完成。之后，向混合物中加入乙酸乙酯和水进行三次萃取。最后，在减压下浓缩溶剂，并使用乙腈洗涤纯化残留物，从而得到5-乙酰基噻吩-2-羧酸。

  烷基芳烃的光诱导深度好氧氧化

  摘要：

  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。
