[reaction: see text] Three fluorous dienophiles have been synthesized, and their value in scavenging an excess diene after Diels-Alderreactions is shown. The resulting fluorous derivatives are separated by solid-phase extraction on fluorous silica gel (FSPE). The fluorous [1,2,4]triazoline-3,5-dione 10 reacted with most dienes within seconds or minutes.
