Synthesis, characterization and study of antibacterial activity of some novel tetrazole derivatives

Orbital: The Electronic Journal of Chemistry, 2011
This work aims at synthesizing novel tetrazole derivatives from phenothiazine. Phenothiazine is first converted into corresponding nitrile by reacting it with aldehyde, sodium metabisulphite and sodium cyanide.

Synthesis of Highly Substituted Oxazoles through Iodine(III)-Mediated Reactions of Ketones with Nitriles

Molecules, 2012
In the presence of trifluoromethanesulfonic acid (TfOH) or bis(trifluoromethane-sulfonyl)imide (Tf2NH), iodosobenzene (PhI=O) efficiently promoted the reactions of dicarbonyl compounds as well as monocarbonyl compounds with nitriles to give 2,4 ...

The Nitrile Bis-Thiol Bioconjugation Reaction

, 2023
Electron-poor aryl nitriles are promising reagents for bioconjugation, due to their high electrophilicity and selectivity for reaction with thiols, albeit generally in a reversible manner.

Nitrile IR intensities characterize electric fields and hydrogen bonding in protic, aprotic, and protein environments

, 2022
Nitriles are widely used as vibrational probes; however, the interpretation of their IR frequencies is complicated by hydrogen bonding (H-bonding) in protic environments.

Reactivity of the biphasic trichloroacetonitrile-CH2Cl2/H2O2 system in the epoxidation of soybean oil

Grasas y Aceites, 2002
In this work we report on the epoxidation of soybean oil by the trichloroacetonitrile -CH2Cl2/H2O2 byphasic system. The reaction was carried out at room temperature and, most importantly, in non acid conditions which prevent the opening of the oxirane ...
