1H,13C, and14N nuclear magnetic resonance study of the hydrogen chloride–NN-dimethylacetamide and hydrogen chloride–N-methylacetamide systems in deuteriochloroform solution

Abstract

Protonation shifts and ¹³C T₁ values in the title systems are reported. Evidence is found for predominant O-protonation and for enhanced intermolecular association in the protonated forms of the amides.
