Attempts to prepare 9,9-dimethyl-9-sila-10(9H)-anthracenone (4a) from dimethylphenyl-2-tolylsilane (5) or 2-bromobenzoic acid as starting compounds via 2-(dimethylphenylsilyl)benzoyl chloride (11a) by condensation with tin tetrachloride resulted in high yields of the title compound 14a.Determination of its structure was only possible by X-ray analysis, determination of the course of the reaction by variation with 2-benzoyl chloride (11b) and mass spectroscopical investigation of the resulting isomeric mixture of bistetramethyldisiloxanes 14b,b',b''.
