Participants

Reaction Steps

To a suspension of 9,10-bis-(4-bromo-phenylethynyl)-9,10-dihydro-anthracene-9,10-diol (2.0 g, 3.5 mmol) in aceton (25 ml), a solution of tin(II)chloride dihydrate (1.82 g, 8.05 mmol) in a mixture of water (15 ml) and acetic acid (15 ml) is added within 15 minutes. The obtained suspension is stirred for another 2.5 hours at ambient temperature, and then the solid is filtered off to give a first crop the title compound. Over night another crop of product crystallizes from the mother liquors, and the combined crops are recrystallized from anisol (30 ml) to give the title compound as orange needles. DSC: mp=305° C. MS: 534 (correct isotope pattern). Elementary analysis: C, 67.45; (calcd. 67.19); H, 3.23; (calcd. 3.01).
