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 or-halo acetates while alkoxyallenes lead to vinyl iodides. In contrast to these results, terminal alkynes commonly afford synthetically valuable l-iodo-alkynes.
