The present invention relates to a method of synthesizing a phenanthrene compound, represented by formula (I), in the presence of a diisopropylamine. The method comprises: in an inert atmosphere, and in the presence of a catalyst, an organic ligand, and a diisopropylamine, reacting in a solvent a compound represented by formula (II) and a compound represented by formula (III) to obtain a compound represented by formula (I), wherein R1 and R2 are independently an H, a C1-C6 alkyl, a C1-C6 alkyloxy or a halogen; R3 is a C6-C10 aryl or a C5-C8 heteroaryl; the C6-C10 aryl or the C5-C8 heteroaryl is optionally substituted with 1-3 substituent groups; and the substituent groups are a C1-C6 alkyl or a halogen. The method obtains a favorable result by selecting a suitable catalyst, an organic ligand, a base, and a solvent, and has a wide prospect for an industrial application. |
