Abstract
The synthesis of a series of α,β-unsaturated disulfoxides having two highly fluorinated chains separated by a polyoxyethylene (POE) group is described. The reaction was carried out in basic medium, and the most relevant feature of this conversion is the enhanced acidity of SO-α-hydrogens of starting materials, leading to the observed regioselectivity.
