| Abstract: | 9-Benzoylanthracene and 9-anthryl styryl ketone disproportionate to anthracene and the corresponding 9,10-diacylanthracene when warmed in carbon disulphide or nitrobenzene with an excess of aluminium chloride. The reactions are co-catalysed by hydrogen chloride. Comparison is made with other 9-anthryl ketones and with 1-naphthyl styryl ketone, which undergo different reactions under similar conditions. The results are interpreted in terms of steric requirements. |
