An interaction of N ‐(cyanomethyl)pyridinium salts with vinamidinium perchlorates or enaminones proceeds as a pseudo‐three component process and results in the formation of 3‐ or 2‐substituted pyrido[2,3‐ b ]indolizine‐10‐carbonitriles, respectively. Optical properties of these compounds have been evaluated, revealing effective green light emission with fluorescence quantum yields of up to 0.81.
