Synthetic Route of C9H9NO4S. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: quinoliniumhydrogensulphate, is researched, Molecular C9H9NO4S, CAS is 530-66-5, about Metal-free photocatalytic aerobic hydroxylation of benzene catalyzed by the commercially available quinoline sulfate. Author is Long, Zhouyang; Sun, Liming; Zhang, Mingjue; Zhang, Yadong; Zong, Chenghua; Xue, Zhiliang; Wang, Tianyu; Chen, Guojian.
Metal-free photocatalytic aerobic hydroxylation of benzene to phenol is achieved by using the low-cost com. available quinoline sulfate (QuH2SO4) as the photocatalyst. The reaction conditions are optimized and a high phenol yield of 11.3% is obtained under the optimal reaction conditions. It is found that the [QuH]+ cation is the catalytic active species and its planar structure is crucial for its effect interaction with benzene. Moreover, the influence of the coupled anion on the photocatalytic activity of the [QuH]+ cation is investigated and discussed.
