Hydrogen-bond-acceptor ligands enable distal C(sp3)-H arylation of free alcoholsThe 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...

In molecular assemblies driven by hydrogen bonds, some acceptor/donor groups are well-known as successful competitors and cause more directional interactions [1]. On the other hand, variety of hydrogen bond assemblies are possible in different crystal structures where the competitions occur between diff...
Fluoride Ion as Ligand and Hydrogen Bond Acceptor: Crystal Structures of Two Dinuclear CuII Complexes Built on a Diazecine Templatecopperdiazecinehydrogen bondTwo dinuclear CuII complexes based on a diazecine ligand were characterized by X-ray diffraction, one of which includes the rare CuII-F...
The hydrogen-bond acceptor ability of divalent sulfur in Y-S-Z systems, Y, Z = C, N, O or S, and the donor ability of thiol S-H have been studied using crystallographic data retrieved from the Cambridge Structural Database. Of 1811 Y-S-Z substructures that co-occur with N-H or O...
bonds (H-bonds) are a specific type of electrostatic interaction between a proton attached to an electronegative atom (such as N or O) and a lone pair of electrons on an electronegative atom such as N, O, or F. The former is called the H-bond donor, the latter the H-bond acceptor....
14.The active area of ENOLASE will potentially exist multi - hydrogen bond of donor and acceptor. ENOLASE烯醇酶活性中心存在多个潜在的氢键给体和受体. 15.In MR - LDHs, interlayer guest adopt - layer arrangement and effect with host through electrostatic force and hydrogen bond. ...
Secondary electrostatic interactions between adjacent hydrogen bonds can have a significant effect on the stability of a supramolecular complex. In theory, the binding strength should be maximized if all the hydrogen-bond donors (D) are on one component and all the hydrogen-bond acceptors (A) are...
The main component of the hydrogen bond is an electrostatic interaction between the dipole of the donor atom with partial negative charge, with the other electronegative atom, the acceptor, bonded to hydrogen atom with partial positive charge. Due to its small size and partial positive charge when...
