A one-pot protocol for the synthesis of 1,2,3-triazoles has been developed starting from inactivated alkenes and based on two click reactions: the azidosulfenylation of the carbon–carbon double bond and the copper-catalyzed azide–alkyne cycloaddition (CuAAC). High yields of the β-methylsulfanyl triazoles have been attained using CuNPs/C as catalyst, with other commercial copper catalysts being completely
从灭活的烯烃开始,基于两个点击反应,开发了一种一锅法合成1,2,3-三唑的方案:碳-碳双键的叠氮磺酰化和铜催化的叠氮化物-炔烃环加成反应(CuAAC )。使用CuNPs / C作为催化剂,已经获得了高产率的β-甲基硫烷基三唑,而其他商用铜催化剂则完全没有活性。甲基硫烷基的多功能性已通过一系列合成转化得到了证明,包括直接获得1-乙烯基和4-单取代的三唑。
