Reactions of Alkenes, Alkynes, and Alkoxyallenes with New Polymer-Supported Electrophilic Reagents

Abstract

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.
