The　reaction　of　a　series　of　sulfonyl-containing　azides　and　terminal　alkynes　indicated　that　the　combination　of　copper　sulfate/substituted　thiourea　was　more　suitable　for　general　copper-catalyzed　azide-end　alkyne　ring　addition　[Cu　(I)　catalyzed　azide-alkyne　cycloaddition,　CuAAC]　reaction.　The　type　of　reaction　was　also　possible　to　efficiently　catalyze　the　synthesis　of　N-sulfonyl-1,2,3-triazole　in　the　aqueous　phase.　The　type　of　reaction　was　not　sensitive　to　water　and　the　yield　was　up　to　99%　in　the　aqueous　phase.　The　reaction　mixture　was　stirred　in　the　air　under　room　temperature　(　25　degrees　C　).　The　novel　system　showed　high　atom-economy　and　functional-group　tolurance.　It　provided　a　simple　and　efficient　synthesis　method　for　the　synthesis　of　a　series　of　N-sulfonyltriazoles.
