Studies on hydrogen bonded complexes Proton transfer equilibria and thermodynamic parameters of hydrogen bonded complexes in 2,4-dinitro-1-naphthol-amine systems

Interaction Site and Proton Transfer Equilibrium in the 4-Aminoantipyrine-Pentachlorophenol Hydrogen–Bonded Adduct

“…The proton transfer equilibrium data are gathered in Table 1. Clearly the value of the 1:1 proton transfer equilibrium constant K PT is low compared to other systems that are reported in the literature 26,27 which could be interpreted in terms of higher steric hindrance of the formed complex together with the lower value of the acidity constant of PCP( ≈ 5.5)…”

Solvation Effect on Proton Transfer Complex Formation between 2,4-Dinitro-1-naphthol and Amines

“…In benzene, DNN reacts with TEA, DEA, Mo, or BnA to form a proton transfer complex, displaying equilibrium constants of 15 488, 1690, 478, and 96 M_1, respectively (Habeeb et al, 1995). This order of equilibrium constants is also found when 2,4-dinitrophenol is reacted with TEA, DEA, Mo, and ra-butylamine (Ye et al, 1988).…”
