Condensation of various dienes with fluoroalkyl vinyl sulfoxides was studied. Four
diastereoisomers were obtained in the case of cyclopentadiene and their structures
were assigned by 2D NMR experiments. Diels-Alder cycloaddition occurred with cyclohexadiene,
in comparison to phenyl vinyl sulfoxide, without thermal extrusion of fluoroalkylsulfenic
acid. Condensation with anthracene led to a mixture of compounds 11 and 12.
