Abstract

Abstract The formation constants and dipole moments of hydrogen-bonded complexes of 1:1 and 2:1 stoichiometry formed between 2,4,6-trichlorophenol and triethylamine are determined in various solvents. The solvent effect on formation and proton transfer equilibria is discussed in terms of continuum dielectric models and the Swain et al acidity (A) parameter of the solvent. The cooperative hydrogen-bonding effects of the second phenol molecule and the hydrogen-donating (electron-accepting) effect of the solvent molecules are demonstrated.
