propose a simple catalytic system based on copper iodide for the reaction with bromoalkenes and bromoalkynes, and based on copper dichloride for the coupling with terminal alkynes. The fluorinated chain was varied from perfluorobutyl to monofluoromethyl. The reaction proceeds efficiently when the unsaturated system is substituted by an aryl or alkyl group. In particular, aliphatic terminal alkynes are efficient
描述了将双键或三键引入 S-全氟烷基亚砜亚胺的氮原子。我们提出了一种基于碘化铜的简单催化体系,用于与溴代烯烃和溴代炔烃的反应,并基于二氯化铜用于与末端炔烃的偶联。氟化链从全氟丁基到单氟甲基不等。当不饱和体系被芳基或烷基取代时,反应有效进行。特别是,脂肪族末端炔烃是这种转化的有效底物。
