Abstract

Owing to mesomerism, which confers to the amide group a partial double bond character, aromatic enamides, a class of compounds in which this chromophore connects two unsaturated systems, possess a marked degree of hexatrienic character. This property induces most of their photochemical reactions and thus irradiation of a great number of these compounds, particularly type a (R# H), type a, R# H type b, R= H results in stilbene- ...
