A copper-catalyzed four-component trifluoromethylthio-arylsulfonylation between styrene derivatives, AgSCF3, aryldiazonium tetrafluoroborates, and ex situ generated sulfur dioxide (from SOgen) is presented. This reaction features mild reaction conditions, good functional group tolerance, a broad substrate scope, good yields, and excellent diastereoselectivity. Preliminary mechanistic studies revealed
介绍了苯乙烯衍生物、AgSCF 3 、芳基重氮四氟硼酸盐和异位生成的二氧化硫(来自 SOgen)之间的铜催化四组分三氟甲硫基-芳基磺酰化反应。该反应具有反应条件温和、官能团耐受性好、底物范围广、收率高、非对映选择性好等特点。初步的机械研究表明,这种转变可能涉及一个激进的过程。
