4,8-Dichloro- and 5,7-dichloro-2,10-dihydroxydicyclohepta[<I>b</I>,<I>d</I>]furan-3,9-diones were synthesized. Although the latter could be obtained by condensation of 4-chloro-<I>p</I>-tropoquinone and its hydroquinone, the former required the hydrolysis of condensate of 3-chloro-<I>p</I>-tropoquinone and 7-chloro-5-hydroxy-2-methoxytropone. This mixed condensation led to several unsymmetrically substituted derivatives in improved yields.
