Heteroaryl thioethers are a class of important bioactive molecules, which exhibit good antibacterial, anti- inflammatory and anticancer activities. In this paper, a new, base-free and green synthesis of heteroaryl thioether in water media is developed. The reaction using alkyl halides and heteroaryl thiols as the starting materials can proceed well at room temperature for 0.5 h, affording the target thioether products in high yields. Compared with the available literature reports, this new method has the advantages of simple operation, mild conditions, less by-product, greeness and high efficiency, broad range of substrates, and etc. Moreover, the reaction can easily be scaled up in gram scale, also showing the good practical value of this new method. Mechanism studies suggested that both the tautomerism of mercaptopyridine to thiopyridone and the hydrogen bond and hydrophobic interaction of water played crucial roles in the reaction.

Key words: heteroaryl thioether, water media, base-free, mild conditions
