Popis:	Photolysis of the title 9,10-dichlorodibenzobarrelene-11,12-diester, (1), results in formation of a semibullvalene, dimethyl 4b,8b-dichloro-4b,8b,8c,8d-tetrahydrodibenzo[a,f]cyclopropa[cd]pentalene-8c,8d-dicarboxylate (2), and an additional photoproduct, dimethyl 4b,10-dichloro-4b,9,9a,10-tetrahydro-9,10-epidioxydibenzo[a,f]pentalene-9,9a-dicarboxylate (3), which contains an unusual peroxo-ring structure. The structures of (1), (2) and (3) have been determined by X-ray analysis
