• General Description: Nitrite (NO??) is an anionic species that can interact with synthetic receptors through hydrogen bonding, particularly involving C-H bonds, as demonstrated in the study. The research highlights the role of C-H hydrogen bonding, especially from polarized Cα-H groups, in enhancing anion binding affinity. While the study primarily focuses on phosphinate recognition, nitrite is among the tested anions, suggesting its potential interaction with receptors designed for anion binding, though the specific affinity for nitrite is not detailed. The findings underscore the broader applicability of C-H hydrogen bonding in anion recognition systems.

Phosphinate selective hosts and importance of C–H hydrogen bonding for affinity modulation toward anion guests

10.1016/j.tetlet.2018.03.066

The research aims to develop selective anion receptors that utilize weak C-H hydrogen bonds, with a focus on phosphinate receptors. Phosphinates are significant in nature due to their association with metabolic diseases and conditions like obesity, NASH, hypercholesterolemia, and diabetes. The researchers designed and synthesized three receptors (1, 2, and 3) that utilize both amide N-H and alpha C-H (Cα-H) to the carbonyl group, differing in the substituent group attached to the alpha carbon, which affects the polarity of the CαH bond and thus the strength of association with anion guests. The study concluded that host 3, with a positively charged pyridinium group, showed the highest binding affinity due to the increased polarity of the Cα-H bond, demonstrating the importance of C-H hydrogen bonding as a modulating element for anionic recognition. Key chemicals used in the synthesis include 1,2-phenylenediamine, acetic acid, cyanoacetic acid, chloroacetyl chloride, pyridine, and various anions for testing, such as dimethyl phosphinate, benzoate, nitrite, and others.
