Paragraph 0030; 0031; 0032, (2019/05/15)
The invention relates to a 2, 5 - diaryl five-membered heterocyclic aromatic preparation method, the method is to turn the diaryl Iodized salt compounds, five-membered heterocyclic aromatic compound, catalyst, ligand, alkali and solvent are mixed uniformly, in 100 °C -140 °C lower sealing reaction for 24 hours, the reaction solution obtained after the reaction is complete; the reaction solution are often gauge extraction, drying, concentration, column chromatography separation to obtain the 2, 5 - diaryl five-membered heterocyclic aromatic compounds. The invention belongs to a pot of reaction of the atom economy, simple operation, high yield, can realize the large-scale production, in functional organic material, biological active compounds and pharmaceutical synthesis of better industrial application prospect.

Wetter is better: The direct arylation of thiazoles on water is quicker, cleaner, and higher-yielding than arylation in organic solvents. The reaction works under mild conditions for an array of aryl iodides, producing 2,5-diaryl thiazoles in excellent yields. Importantly, novel bi-heteroaryl compounds are produced without the requirement for stoichiometric organometallic coupling agents. (Figure Presented).
