Reaction of anthracene radical anion with BeCl2 in THF gives a crystalline polymeric organometallic compound that yields 9,9',10,10'-tetrahydro-9,9'-bianthryl (THBA) on hydrolysis.Hydrolysis with D2O gives exclusively trans-10-d, trans-10'-d hydrocarbon.Reaction of anthracene dianion with BeCl2 in THF leads to cleavage of the solvent and formation of cis-9,10-dihydro-9,10-bis(4-hydroxybutyl)anthracene.Comparable reactions of cyclooctatetraene dianion are also discussed.The results point up the covalence of the carbonberyllium bond.
