Equilibrium constants for electron-donor–acceptor complexes formed between hexamethylbenzene and 1,3,5-trinitrobenzene in carbon tetrachloride solution determined by 13C nuclear magnetic resonance chemical shifts

Abstract

Separate experiments, based on ¹³C and ¹H chemical-shift measurements, respectively, for the system hexamethylbenzene (D)+ 1,3,5-trinitrobenzene (A) in carbon tetrachloride under the condition [D][A] have yielded constants K₁(for D + A ⇌ DA) and K₂(for DA + D ⇌ D₂A) which are in close agreement.
