their diverse biological activities and medicinal prospects. Here, a facile method was reported. An arylation of 1,3,4-oxa(thia)diazol-2-thiones reacting with arynes to build C(aryl)-S bonds in the presence of CsF had good yields and excellent selectivity. The reaction was completed in short time without using expensive reagents and catalysts. Present reaction system is an efficient procedure to process
