报道了一种无金属、操作简单、高效的室温下CBr4可见光催化亚甲基芳烃好氧光氧化合成芳香醛的方法。该反应是高度选择性的，因为它进行时没有任何过度氧化为羧酸。可见光和分子氧的利用廉价、容易获得、无毒，可持续试剂使该协议符合绿色化学要求。还提供了一种从亚甲基芳烃中生成醛的可能的机理。
A metal-free, operationally simple and efficient means of aerobic photooxidation of methylarenes to aromatic aldehydes at room temperature employing visible light photocatalysis with CBr4 is reported. The reaction is highly selective as it proceeds without any over oxidation to carboxylic acids. The utilisation of visible light and molecular oxygen is inexpensive, readily available, non-toxic and the sustainable reagents make the protocol compatible with green chemistry demands. A plausible mechanism for the formation of aldehydes from methylarenes is also provided.
