Paragraph 0030-0031, (2021/01/15)
The invention discloses a method for preparing 8-quinoline carboxylic acid and derivatives thereof, which comprises the following steps: by using a compound I as a raw material, reacting with an oxidant at the temperature of 50-150 DEG C under normal pressure in a solvent under the action of a Cu-Co-X ternary composite catalyst to obtain a compound II; according to the method, the efficient Cu-Co-X ternary composite catalyst is adopted, the reaction is carried out at the temperature of 50-150 DEG C under normal pressure, the reaction condition is mild, the oxidation yield is remarkably increased, near-zero emission of three wastes is realized, the pollution problem is effectively solved, and the production cost is greatly reduced.

Swapped: Commercially available quinolinone derivatives (1 or 2, see scheme) were reacted with arylboronic acids in the presence of a RhI complex to give aryl(quinolin-8-yl)methanone products 3 in medium to good yields. A mechanism that involves the in situ oxidation of RhI to RhIII by O2 in the presence of CuI was proposed. Copyright
