The invention relates to a method for synthesizing a phenanthrene compound, as shown by formula (I) below, in a sodium bicarbonate environment. The method comprises the following steps: reacting a compound as shown by formula (II) below and a compound as shown by formula (III) in a solvent under an inert atmosphere in the presence of a catalyst, an organic ligand and sodium bicarbonate, and thereby obtaining the compound of formula (I), wherein R1 and R2 are each independently H, C1-C6 alkyl, C1-C6 alkoxy or halogen; and R3 is C6-C10 aryl or C5-C8 heteroaryl, wherein the C6-C10 aryl or C5-C8 heteroaryl is optionally substituted by 1-3 substituents, and the substituents are C1-C6 alkyl or halogen. The method achieves good effects due to the selection of a suitable catalyst, organic ligand, base and solvent, and has wide industrial application prospects. |
