The reactivity of 1-methylthio-1-(p-tolylsulfonyl)ethene (1) as a dienophile in Diels–Alder chemistry is investigated. Cycloaddition reactions were carried out with a range of pyran-2-ones and isobenzofurans. The initial Diels–Alder adducts have the potential of undergoing fragmentation in chemistry that is relevant to the design of anticancer intercalator prodrugs. The nature of the final products
Amine derivatives of benzoylbenzoic acid, benzoylbenzoic acid esters and salts were prepared, which are suitable as photo initiators for UV & LED curable compositions. The derivatives are compounds of Formula I, Ia, and II wherein R
