Abstract
N-arylsulfonyl-1,2,3-triazoles were synthesized from 1,1-dibromo-2-arylethylenes via a one-pot reaction involving the Cs2CO3-mediated dehydrobromination process of the dibromoalkenes to produce alkynes followed by the Cu(I)-catalyzed Huisgen cycloaddition of the alkyne intermediates with tosyl azide.

通过Cs2CO3介导的1,1-二溴-2-芳基乙烯的脱溴化反应,从1,1-二溴-2-芳基乙烯合成了N-芳基磺酰基-1,2,3-三唑,生成炔烃,然后通过Cu(I)催化的Huisgen环加成反应将炔烃中间体与对甲苯磺酰基叠氮化合物进行环加成。
