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, resp. Optical properties of these compounds have been evaluated, revealing effective green light emission with fluorescence quantum yields of up to 0.81. In the experiment, the researchers used many compounds, for example, 1-(Cyanomethyl)pyridin-1-ium chloride (cas: 17281-59-3Product Details of 17281-59-3).
1-(Cyanomethyl)pyridin-1-ium chloride (cas: 17281-59-3) belongs to pyridine derivatives. Pyridine has a conjugated system of six π electrons that are delocalized over the ring. The molecule is planar and, thus, follows the Hückel criteria for aromatic systems. Halopyridines are particularly attractive synthetic building blocks in a variety of cross-coupling methods, including the Suzuki-Miyaura cross-coupling reaction.Product Details of 17281-59-3
