Abstract
Rearrangement of triethyl-and tetrabutyl-ammonium salts in chloroform solution has been revealed from the characteristic features of the ν(N+H) bands caused by Fermi resonance interaction. Temperature changes of the i.r. spectra show this process to be reversible. Rearrangement constants K1 and K–1 and enthalpies –ΔH(for some cases only) of this process have been determined by measuring the total integrated intensities of the ν(N+H) bands of complexes which are in equilibrium. K1 values of the tetrabutylammonium salts increase with decreasing hydrogen bonding strength in triethylammonium salts. The measured enthalpies of rearrangement and those calculated from the ν(N+H) bands of hydrogen-bonded complexes studied are in agreement. It has also been shown that tetrabutylammonium salt anions can participate in the rearrangement of hydrogen-bonded ion pairs like the organic bases studied previously.
