| titleOfInvention | Method for preparing polysubstituted 1-naphthoic acid compound under catalysis of ruthenium |
| abstract | The invention belongs to the technical field of organic synthesis, and discloses a method for preparing a polysubstituted 1-naphthoic acid compound by ruthenium catalysis. Phthalic acid (I) or phthalic anhydride compounds (II) and diaryl substituted symmetrical alkyne compounds (III), ruthenium catalysts, additives and solvents are heated to react in the air or oxygen environment, and reaction products are separated and purified to obtain the polysubstituted 1-naphthoic acid compounds (IV). The method uses phthalic acid or phthalic anhydride compounds and alkyne which are easy to obtain as raw materials, and the high catalytic activity of the ruthenium catalytic system enables the reaction to use air or oxygen as a green oxidant, thereby avoiding the use of toxic, dangerous or expensive oxidants, having simple, convenient and safe reaction operation, and being convenient for realizing industrialization. |
