A novel high-yielding Zn/CuI-mediated coupling method of alkyl halides with vinyl sulfones, vinyl sulfonates, and vinyl sulfonamides is described. This protocol is applicable for primary, secondary, and tertiary alkyl iodides and bromides. Alkyl chlorides and aryl and vinyl halides were unreactive under the reaction conditions. Formamide was found to be a superior solvent for obtaining high yields
描述了一种新颖的高产Zn / CuI介导的烷基卤与乙烯基砜,乙烯基磺酸盐和乙烯基磺酰胺的偶联方法。该协议适用于伯,仲和叔烷基碘和溴化物。烷基氯与芳基和乙烯基卤化物在反应条件下不反应。发现甲酰胺是获得高产率的优良溶剂。
