steric requirements of the acylation species. Competitive Perrier acetylation of 2,3-dimethylnaphthalene and naphthalene in chloroform solution gives the following relative reactivities of the nuclear positions: 1-naphthyl 1·00, 2-naphthyl 0·31, 2,3-dimethyl-1-naphthyl 1·59, 2,3-dimethyl-5-naphthyl 7·14, and 2,3-dimethyl-6-naphthyl 3·68. The corresponding values for benzoylation are 1·00, 0·04, 172, 38·2
