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.

A sequential cross-coupling/annulation of ortho-vinyl bromobenzenes with aromatic bromides was realized, providing a direct and modular approach to access polycyclic aromatic compounds. A vinyl-coordinated palladacycle was proposed as the key intermediate for this sequential process. Excellent chemoselectivity and regioselectivity were observed in this transformation. The practicability of this method is highlighted by its broad substrate scope, excellent functional group tolerance, and rich transformations associated with the obtained products.

A palladium-catalyzed cross-dehydrogenative coupling of phenanthrenes with simple arenes was developed. This protocol provides an opportunity for producing π-extended polycyclic aromatic hydrocarbons with minimum waste and high atomic efficiency under mild and ligand-free conditions.

Direct CH bond arylation of arenes with aryltrimethylsilanes catalyzed by PdCl2 in the presence of CuCl2 as an oxidant has been developed. In addition to the role as the oxidant, CuCl2 is found to be necessary for the selective crosscoupling reaction.
