Transmission of the inductive effect in pyrrole derivatives was investigated on 2-ethylpyrrole (VIa), 2-methylpyrrole (VIb), 2-dimethylaminopyrrole (VIc), 2-hydroxymethylpyrrole (VId), methyl 2-pyrrolylacetate (VIe), 2-pyrrolylacetonitrile (VIf), 2-benzenesulfonylmethylpyrrole (VIg) and trimethyl(2-pyrrolylmethyl)ammonium iodide (VIh), by comparison of their relative basicities and acidities.These were determined by IR spectroscopy from the strength of donor-acceptor interactions of the pyrrole derivatives with suitable standard compounds.The found differences show good linear correlations with the ?I substituent constants.On this basis, the transfer of the inductive effect in the given pyrrole series appears to be proportional.
