Abstract | {A study of the photochemistry of the title 9-phenyl-dibenzobarrelene-11,12-diester (1) reveals the formation of a semibullvalene derivative, dimethyl 8b-phenyl-4b,8b,8c,8d-tetrahydrodibenzo[a,f]cyclopropa[cd]pentalene-8c,8 d-dicarboxylate (2), in acetone solution, with an additional cyclooctatetraene (COT) photoproduct, dimethyl 5-phenyldibenzo[a,e]cyclooctene-6,12-dicarboxylate (3), in acetonitrile, benzene and in solid-state photolysis. Crystal data: T = 294 K, Cu Kalpha |
