Synthesis of Organic Nitrogen Heterocyclic Salts

Abstract

New (pyrrolyl)-pyridinium and quinolinium salts have been prepared selectively in high yields by reacting (pyrrolyl)-pyridine or -quinoline and their derivatives with CF₃SO₃CH₃ in CH₂Cl₂. No methylation of the nitrogen of pyrrole was observed. Preliminary investigations revealed that these salts show a good response as nonlinear optics.

Key words

pyrrole - polypyrrole - pyridinium - quinolinium - meth­ylation - S_RN1 - Hyper-Rayleigh Scattering
