different aromatic compounds 1a–1t with iodine and a mercury(II)-salt 2 [mercury(II) chloride, nitrate or triflate] (1:1:1 molar ratio) in dichloromethane at room temperature leads to the corresponding iodoarene 3, the obtained regiochemistry being the expected. Concerning the mercury(II) salt, the observed reactivity decreased in the series triflate&>nitrate&>chloride according to their ionic character.
室温下,不同的芳族化合物1a – 1t与碘和汞(II)盐2 [氯化汞,硝酸盐或三氟甲磺酸盐](摩尔比为1:1:1:1)在二氯甲烷中的反应生成相应的碘芳烃如图3所示,所获得的区域化学是预期的。关于汞(II)盐,根据三氟甲磺酸盐>硝酸盐>氯化物系列的离子特性,观察到的反应性降低。汞(II)盐激活碘分子,然后与芳族化合物进行S E反应是可能的机理。
