Cohalogenation of Allyl and Vinylsilanes using Polymer-bound Haloate(I)-Reagents

Polymer-supported electrophilic halogenate(I) complexes 2 and 3 promote smooth addition to vinyl and allylsilanes without loss of the silyl group. In conjunction with Amberlyst A26 (OH？ -form) vinyl silanes are converted into epoxysilanes.
