Abstract
1-(N,N-diethylcarbamoyloxy-2-fluoro-2-(phenylsulfonyl)-ethene has been prepared and reacted with a variety of dienes to give fluorinated [4+2] cycloadducts. In contrast, the desulfonated equivalent 1-(N,N-diethylcarbamoyloxy)-2-fluoro-E-ethene reacts with cyclopentadiene alone, to give mixtures of [4+2] and [2+2] cycloadducts.
