摘要：

The irradiation of alkenyloxyphenol and alkenyloxydihydroxybenzene derivatives furnishes benzocyclobutenes and rearranged products in high yields, when the reaction is carried out in the presence of acid. Under the same reaction conditions the photochemical conversion of a-alkenyl derivatives of salicylic acid yields tricyclic non aromatic products possessing a cyclobutene moiety. Bicyclic and tricyclic beta-alkoxy-alpha,beta-unsaturated ketones are obtained from the irradiation of 3,5-dihydroxybenzoic acid derivatives in the presence of sulphuric acid.
