Procedimiento

A solution of 15.0 g. of 2-chloroanthracene in 60.8 g. of vinylene carbonate is refluxed for 20 hours and then vacuum distilled. The residue is recrystallized from methylene chloride-methanol giving cis-2-chloro-9,10-dihydro-9,10-ethanoanthracene-11,12-diol, cyclic carbonate as gray crystals, m.p. 200°-230° C.
