In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Metal-free photocatalytic aerobic hydroxylation of benzene catalyzed by the commercially available quinoline sulfate, published in 2019-03-05, which mentions a compound: 530-66-5, mainly applied to photocatalytic aerobic hydroxylation benzene quinoline sulfate, Category: thiazolidine.
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.
Here is just a brief introduction to this compound(530-66-5)Category: thiazolidine, more information about the compound(quinoliniumhydrogensulphate) is in the article, you can click the link below.
