Sažetak
Heteroassociation of 2,3,4,5-tetraiodopyrrole and its bromo and .
chloro analogues with acetone, tetrahydrofuran, pyridine, dimethyl
sulphoxide, and hexamethylphosphorictriamide in carbon tetrachloride
was studied by means of infrared spectroscopy. Values of
the formation constants for 1 : 1 complexes and the ~vNH frequency
shifts of these acid-base pairs are reported. The proton
donor strengths of the halogenated pyrroles were found to be of
the same order of magnitude as that of phenol. In most cases the
structure of the bonded NH stretching absorption is irregular,
containing several maxima and minima. The reasons for this irre·gularity
are discussed.
