A novel and efficient Rh/O2 catalytic system has been developed and shown to catalyze highly efficient oxidative C-H activation/annulation reactions, producing a broad range of isoquinolinium salts with high turnover numbers (up to 740). Mechanistic studies provided strong evidence of facile oxidation of Rh(I) to Rh(III) by molecular oxygen facilitated by acid.

The invention discloses a substituted isoquinolinium salt preparation method which is as follows: using oxygen as an oxidant and various substituent group-substituted aromatic hydrocarbons, alkynes and acids as starting materials for catalysis with transition metals to obtain a compound containing an isoquinolinium salt structure. The reaction raw materials, oxidant and catalyst are cheap, the synthesis process is simple, the synthetic cost is greatly reduced; reaction condition is mild, the yield is high, industrialization is easy; the reaction raw materials and the catalyst are clean, nontoxic and low in pollution to environment. The compound and derivatives thereof as important fine chemicals can be widely used in medicines, pesticides, flavors and photoelectric and other industries.
