Paragraph 0116; 0130-0132; 0134; 0136, (2020/12/10)
The invention discloses a preparation method of a fused ring compound III. The preparation method comprises the following step: in a solvent and in the presence of palladium acetate, alkali and a ligand, carrying out a reaction shown in the specification on a compound I and a compound II to obtain a compound III. The preparation method disclosed by the invention is relatively good in compatibilitywith a substrate, various polycyclic aromatic hydrocarbon compounds can be simply obtained in a short period of time through convergent synthesis, and particularly, heteroatom-containing polycyclic aromatic hydrocarbon shows extremely excellent regioselectivity.

An efficient entry into densely substituted fluorinated and perfluoroalkylated benzene derivatives via chemo- and regioselective Pd-catalyzed [4 + 2] cross-benzannulation is presented. The synthetic utility of these products for the synthesis of various aromatic and heteroaromatic compounds is also demonstrated. This strategy offers a viable and quite general alternative to existing fluorination and perfluoroalkylation methods for securing these valuable molecules.
