74 g (0.5 mole) of phthalic anhydride and 134 g (1.10 moles) of AlCl3 were reacted with 20 g (0.2 mole) of triethylboron in 74 g of tert-amylbenzene for 8 hours, as described in Example 1. After the mixture had been worked up in a conventional manner, 127 g (86% of theory) of a mixture of 2-(4'-tert-amylbenzoyl)-benzoic acid and 2-(4'-sec-isoamylbenzoyl)-benzoic acid (tertiary/secondary ratio=60:40) were obtained.
