Abstract

The addition of maleic anhydride to asymmetrical diphenylethylene, first observed by Wagner-Jauregg, 2 is a most peculiar example of Diels-Alder condensation for two reasons. In the first place, it shows that under specific structural conditions conjugation of a benzene ring with an exocyclic double bond gives a reactive dienic system, whereas styrene itself forms only copolymers with maleic'anh~ dride.~ This behavior is undoubtedly due to ...
