Moderate yields were always obtained due to the nature and reactivity of both carbohydrate lactols and selenium-based olefinating reagents under the conditions tested.

Abstract A facile method has been developed for the solid-phase organic synthesis of ( E )-vinyl phenyl selenides from polymer-supported phenylselenenylmethyl sulfone. The advantages of this method include straightforward, convenient and odorless procedures, high product yields, and good stability of this new polymeric reagent.
