Reaktionsschritte
Employing the procedure substantially as described in Example 1, Steps A through D, but substituting for the 5H-dibenzo[a,d]cyclohepten-5-one used in Step A thereof an equimolecular amount of 3-bromo-5H-dibenzo-[a,d]cyclohepten-5-one, 3-chloro-5H-dibenzo[a,d]cyclohepten-5-one, or 3-fluoro-5H-dibenzo[a,d]cyclohepten-5-one, and o-chlorobromobenzene as solvent in Step B, there are produced, respectively, 2-bromo-6,12-dioxo-5,6,7,12-tetrahydrodibenzo[a,d]cyclooctene, m.p. 133°-138° C., 2-chloro-6,12-dioxo-5,6,7,12-tetrahydrodibenzo[a,d]cyclooctene, m.p. 148°-149° C., and 2-fluoro-6,12-dioxo-5,6,7,12-tetrahydrodibenzo[a,d]cyclooctene.
