ABSTRACT

Enthalpies of dissolution of pyrrole, N-methylpyrrole in proton acceptor solvents and proton acceptorsin the medium of pyrrole, N-methylpyrrole were measured. The enthalpies of hydrogen bond of pyrrole,N-methylpyrrole with proton acceptors were calculated from experimental data of solution enthalpy ofamines with organic compounds. The hydrogen bond enthalpies of proton acceptors with N- methylpyr-role are equal to zero unlike with pyrrole. The hydrogen bond enthalpies of proton acceptors (B) in pyrroleare significantly lower than the enthalpies of hydrogen bonding of systems of pyrrole-base in the com-plexes 1:1 due to reorganization effects of pyrrole as solvent. The cooperative effects in multi-particlecomplexes of pyrrole with bases are negligible.
