Thermal Retrograde Aromatization of Caged Bicycloocta-2,4-diene Derivatives

Article abstract of DOI:10.1021/jo00326a015

The question of thermal frangibility of bicyclo<4.2.0>octa-2-diene moieties located within strained caged molecules is examined.For this purpose, the urazoles 6, 10, 14, and 17 were prepared and individually converted by halogenation-dehydrohalogenation i
