ABSTRACT:
The use of vinyl sulfides, sulfoxides and sulfones in synthetic chemistry for the production of a wide variety of materials is well known. For example, phenyl vinyl sulfides, sulfoxides and sulfones have been used for the synthesis of important heterocycles, in combinatorial chemistry and as Diels-Alder adducts. Although these compounds have been used extensively for a variety of applications, the isotopically labeled versions have not been reported. A simple route for the isotopically labeled production of these important building blocks has been developed.
