When small amounts of a good hydrogen-bond acceptor such as pyridine or THF are added to a nonpolar swelling solvent such as chlorobenzene or toluene, there is a very rapid increase in coal swelling with increasing acceptor concentration which presently almost levels off. When swelling is plotted...

hydrogen bond A chemical bond in which a hydrogen atom that is already bonded to an atom in a molecule forms a second bond with another atom, either in the same molecule or in a different one. The second atom is usually of a type that strongly attracts electrons, such as nitrogen or ox...
The functionalization of C–H bonds in organic molecules is one of the most direct approaches for chemical synthesis. Recent advances in catalysis have allowed native chemical groups such as carboxylic acids, ketones and amines to control and direct C(sp
Hydrogen bondsare found in proteincrystallographyindirectly. If a properhydrogen bondacceptor–donor pair is within the correct distance, the bond is taken to be ahydrogen bond. This distance is generally considered to be from 2.7 to 3.3 Å, with 3.0 Å being the most common value for prote...
Three new N 2O heteroscorpionate ligands designated L6OH, L7OH and L9OH, containing either appended hydrogen bond donating or accepting residues have been synthesized and characterized. Metal complexes of these ligands with Co(II) and Ni(II) have been characterized by X-ray crystallography. A ...
