1-氰基-2-（2，2-二氰基-5-苯基戊炔-4-基）萘及其类似物的光辐射促进了顺序的分子内[2π + 2π]光环加成和环丁烯开环形成苯并环辛四烯，然后通过光化学跨环环化过程以良好的产率转化为苯并三醌。
Photoirradiation of 1-cyano-2-(2,2-dicyano-5-phenylpentyn-4-yl)naphthalene and its analogues promotes sequential intramolecular [2π + 2π] photocycloaddition and cyclobutene ring opening to form benzocyclooctatetraenes, which are then transformed to benzotriquinanes in good yields via a photochemical transannular cyclization process.
