Solvent and substituent effects on fluorine-19 chemical shifts in some 5-substituted 2-fluoropyridines was written by Giam, Choo-Seng;Lyle, James L.. And the article was included in Journal of the Chemical Society [Section] B: Physical Organic in 1970.Name: 6-Fluoronicotinonitrile This article mentions the following:
The 19F NMR chem. shifts of several 5-substituted 2-fluoropyridines in 4 widely different solvents have been measured. The effects of solvents and substituents on the shifts paralleled those in the benzene series with certain modifications. In the experiment, the researchers used many compounds, for example, 6-Fluoronicotinonitrile (cas: 3939-12-6Name: 6-Fluoronicotinonitrile).
6-Fluoronicotinonitrile (cas: 3939-12-6) belongs to pyridine derivatives. Pyridines are an important class of heterocycles and occur in polysubstituted forms in many naturally occurring biologically active compounds, drug molecules and chiral ligands. 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.Name: 6-Fluoronicotinonitrile
