The reaction of mercury(II) salts (fluoride, chloride, bromide, nitrate methanesulphonate, toluene-p-sulphinata, and toluene-p-sulphonate) and halogens (bromine or iodine) with alkenes leads to the corresponding 1,2-bifuctionalized products resulting from the addition of the halogen and the mercury(II) salt anion selectively.
汞(II)盐(
氟化物、

溴化物、
甲磺酸硝酸盐、
对甲苯磺酸盐和
对甲苯磺酸盐)和卤素(
溴或
碘)与烯烃反应时,卤素和
汞(II)盐阴离子选择性地加入,会产生相应的 1,2-双反式化产物。
