A convenient synthesis of perfluoroalkylated indolizinylphosphonates was written by Shen, Yanchang;Zhang, Yuming;Jiang, Guo-Fang. And the article was included in Synthesis in 2002.HPLC of Formula: 17281-59-3 This article mentions the following:
A convenient method for the synthesis of perfluoroalkylated indolizinylphosphonates via the 1,3-cycloaddition of pyridinium N-ylides and perfluoroalkynylphosphonates in 49-77% yields is described. In the experiment, the researchers used many compounds, for example, 1-(Cyanomethyl)pyridin-1-ium chloride (cas: 17281-59-3HPLC of Formula: 17281-59-3).
1-(Cyanomethyl)pyridin-1-ium chloride (cas: 17281-59-3) belongs to pyridine derivatives. In contrast to benzene, Pyridine’s electron density is not evenly distributed over the ring, reflecting the negative inductive effect of the nitrogen atom. Several pyridine derivatives play important roles in biological systems. While its biosynthesis is not fully understood, nicotinic acid (vitamin B3) occurs in some bacteria, fungi, and mammals.HPLC of Formula: 17281-59-3
