(matrix presented) Preparation of new polymer-supported electrophilic reagents that efficiently promote 1,2-haloacetoxylations of alkenes and alkoxyallenes is described. Under very mild conditions and in high yields, alkenes are transformed into α-halo acetates while alkoxyallenes lead to vinyl iodides. In contrast to these results, terminal alkynes commonly afford synthetically valuable 1-iodo-alkynes. ? Technischen Universitaet Clausthal. ? Willamette University.

The Pb(OAc)4-I2-CF3COOH oxidizing system was discovered, and its reactions with alkenes (cyclohexene, 1-hexene, styrene) in 1,2,2-trifluorotrichloroethane led to the selective formation of β-iodoalkyl trifluoroacetates or the ditrifluoroacetates of diols.In the reaction with 1-hexene a third direction is possible, i.e., the formation of the mixed acetic acid and trifluoroacetic diesters of 1,2-hexanediol.During the oxidation of styrene the formation of the geminal diester 1,1-ditrifluoroacetoxy-2-phenylethane is observed.The reaction takes place with the intermediate formation of compounds of monovalent iodine or a complex of polyvalent iodine, depending on the ratio of the reagents.
