Reactions and properties of the isomeric dihydrothiophene 1, 1- dioxides
(Virginia Polytechnic Institute, 1957)
Sulfur dioxide and 1,3-butadiene react to form a five-membered cyclic unsaturated sulfone. the 2,5-dihydrothiophene 1,1-dioxide (I). When treated with a base, I will isomerize to form the 2,3-dihydrothiophene 1,1- dioxide ...
