Abstract

Three derivatives of 9,9′-biacridine, 2,2′-dihydroxy, 2,2′-dimethoxy and 2,2′-diacetoxy have been prepared. The crystal structure of racemic 2,2′-dimethoxy-9,9′-biacridine CHCl3 1:1 complex has been determined and shows an almost perpendicular conformation of both acridine rings. 1H NMR experiments using the diacetoxy derivative and both Eu(tfc)3 and R-Pirkle's alcohol show the splitting of some signals characteristic of a racemic compound.
