4,4'-Binaphthylidene-1,1'-diones - Colour and Structure

Synthesis and properties of various 4,4'-binaphthylidene-1,1'-diones are described.The UV spectra of the deep red to purple diones may be calculated on the base of substituent increments.The experimental values of the analyzed substituents can be reproduced using PPP calculations with satisfying accuracy, which makes it possible to predict also absorption maxima of hitherto unknown 4,4'-binaphthylidene-1,1'-diones.Keywords: 4,4'-Binaphthylidene-1,1'-diones, Phenol Oxidation
