Paragraph 0050; 0051; 0052; 0053, (2016/10/10)
The invention relates to a synthetic method for quinone aryl thioether compounds represented by a formula (III). The method comprises the following steps: in an organic solvent, in the presence of a catalyst, an oxidizing agent, an organic ligand and an accelerant, performing a reaction on a compound represented by a formula (I) and a compound represented by a formula (II) for 6-10 hours at 50-70 DEG C; after reaction, performing post-treatment to obtain the compound represented by a formula (III) as shown in the description, wherein R is selected from H, C1-C6 alkyl, C1-C6 alkoxyl, halogen or nitryl. Through comprehensive screening and synergistic effect of the catalyst, the oxidizing agent, the organic ligand, the accelerant and the organic solvent, the method can obtain the targeted product at a high yield. The invention provides a brand-new synthetic method for the compounds and has good application values and industrial production potentials.
