Abstract
New (pyrrolyl)-pyridinium and quinolinium salts have been prepared selectively in high yields by reacting (pyrrolyl)-pyridine or -quinoline and their derivatives with CF 3 SO 3 CH 3 in CH 2 Cl 2 . No methylation of the nitrogen of pyrrole was observed. Preliminary investigations revealed that these salts show a good response as nonlinear optics.
