Descriptors of hydrogen-bond basicity (enthalpy of hydrogen-bond formation, hydrogen-bond length and minimum electrostatic potential of the base) have been calculated by the AM1 and PM3 methods for hydrogen-bond formation between 4-fluorophenol and numerous nitriles embracing a large range of structur...
To fulfil this aim, we have synthesized a series of fluorinated amides using 3-methoxyphenylacetic acid and fluorinated anilines and studied their structural properties through single crystal and powder X-ray diffraction methods. Our results indicated that the "organic fluorine" plays a significant ...

B, the putative interaction of alkylamides with the CB2 receptor is shown. The oxygen atom in the hydroxyl group of Tyr-190 forms a hydrogen bond with the amide hydrogen of the alkylamide (shown by yellow line in B), and the aromatic ring of Tyr-190 exhibits π -π interactions with ...
The complexes were successfully applied as catalysts for hydration of nitriles to amides. Using one of the complexes, a wide range of aryl/heteroaryl ... A Puzari,D Borah,P Das - 《Monatshefte Fur Chemie》 被引量: 0发表: 2022年 加载更多0关于...

It has been found that hitherto unknown derivatives of dihydro-pyridone can be obtained if strong acids, in presence or absence of a solvent, are caused to act on nitriles or amides of derivatives of a-cyano-y-acetyl-glutaric acid mono ester prepared by reacting :aldehydes simultaneously with...
CONTROLS NOTE:Important charges and non-bonding electrons are shown throughout the animation except during the transition phase Click the structures and reaction arrows to view the 3D models and animations respectively The increase in reaction rate indicates that neighbouring group particiaption is takin...
