Solid phase polymeric analogue of benzyltriethylammonium dichloroiodate and dibromoiodate reagents have been prepared and used as recyclable reagents for synthetic transformations on some organic substrates. The development of these reagents involve polym
BROMO- AND IODOFUNCTIONALIZATION OF OLEFINS BY MEANS OF THE MERCURY(II) SALT-HALOGEN COMBINATION

Mercury(II) salts (fluoride, chloride, bromide, formate, acetate, trifluoroacetate, propionate, benzoate, nitrate, methanesulphonate, toluene-p-sulphonate, thiocyanate, and toluene-p-sulphinate) reacted with monoolefines and bromine or iodine to give 1,2-bifunctionalized products resulting from the addition of the halogen and the mercury(II) salt anion selectively.The addition was regiospecific for styrene and for 3,3-dimethylbut-1-ene affording Markownikoff type products, respectively.In the case of hex-1-ene both regioisomers were obtained.For cyclic alkenes trans-1,2-derivatives were stereoselectively obtained.Cycloocta-1,5-diene gave the monoaddition products.Buta-1,3-diene underwent mainly 1,2-addition and allylic derivatives gave the corresponding 1,2,3-trifunctionalized compounds.A possible ionic mechanism is proposed to explain the obtained addition products.
