Kinetics of protiodeacylation of 1-benzoylnaphthalene and its homologues in 89.8% sulphuric acid

Abstract

The kinetics of protiodebenzoylation in 89.8%(w/w) sulphuric acid have been measured for 1-benzoylnaphthalene and some of its methyl and dimethyl derivatives. Relative rate coefficients, calculated for 330 K, were (substituents in the naphthalene ring, relative rate): H, 1.00; 2-Me, 11.8; 4-Me, 96.2; 2,3-Me₂, 26.1; 2,4-Me₂, 67 000; 2,6-Me₂, 6 070; and 2,7-Me₂, 13 800.
