Versuchsvorschrift

A solution of 2.38 g. (0.01 mole) of cis-9,10-dihydro-9,10-ethanoanthracene-11,12-diol [Newman et al., J. Am. Chem. Soc., 77, 3789 (1955)] in 50 ml. of glacial acetic acid was stirred magnetically at 30°-35° C. and treated portionwise with 8.9 g. (0.02 mole) of lead tetra-acetate or until a blue color persisted with starch-iodide test paper. The reaction mixture was stirred for two hours and the so-formed orange crystals were removed by filtration and recrystallized from methylene chloride giving 1.5 g. (65%) of orange needles, m.p. 245°-247° C.
