Notizen:
Two atropisomers, ap and sc*(9S*), of the title compound [8-chloro-1,4-dimethyl-9-(2-methylbenzyl)-9,10-dihydro-9,10-o-benzenoanthracene, C30H25Cl] have been isolated and their structures determined by X-ray diffraction. The structures of the two isomers are essentially the same as those of the analogous bromo derivatives. The crystal of the sc*(9S*) isomer decomposed when it was heated to 493 K, owing to the sc–ap transition.
