The mercury(II) salt–halogen combination HgX2–Hal2: a versatile reagent for stereoselective addition of Hal–X to alkenes
Abstract
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.
