NUCLEAR MAGNETIC RESONANCE STUDIES OF THE PROTONATION OF WEAK BASES IN FLUOROSULFURIC ACID: V. KETONES, CARBOXYLIC ACIDS, AND SOME OTHER OXYGEN BASES

Abstract

The proton n.m.r. spectra of the conjugate acids of some ketones and carboxylic acids, and of ethyl acetate, nitromesitylene, and ethyl alcohol have been observed. A correlation has been found between the chemical shift of the C=OH + proton of the conjugate acids of some para-substituted acetophenones and their pK BH + and σ + values. The rates of proton loss from these conjugate acids have been obtained.
