The surge of photocatalytic transformation not only provides unprecedented synthetical methods, but also triggers the enthusiasm for more sustainable photocatalysts. On the other hand, oxygen is an ideal oxidant in...
A novel and efficient I2-promoted oxidative coupling of acetophenes with amines to α-ketoamides is presented, which employs molecular oxygen as an environmentally friendly oxidant under metal-free conditions.
An efficient, operationally simple, metal-free strategy for the selective oxidation of methylarenes to aromatic aldehydes through visible light photocatalysis employing CBr4 and molecular oxygen is reported.
Quinone-amine polymers can be employed as a metal-free and reductant-free catalyst for the hydroxylation of benzene to phenol and can yield phenol as high as the transition metal catalyst.
The efficient metal-free oxidative coupling of arylmethylamines with indoles has been developed using molecular oxygen as a green oxidant towards a novel rout of 3,3′-bis(indolyl)methanes (BIMs) synthesis.
