摘要

Simple stirring of polymer-supported selenium bromide 1 in THF at room temperature with a excess of anhydrous ethene resulted in a rapid decolorization of the resin (less than five minutes) to produce a yellow β-bromoethyl selenide resin 2 in nearly quantitative yield, as monitored by FT-IR spectroscopy showing a moderate strong C-Br absorption at 572 cm -1 . Resin 2 can be stored at room temperature for long time without diminution of capacity or the liberation ...
