Die Boran Triphenylphosphine Komplex ist ein Beispiel für ein Lewis-Addukt, wobei eine Lewis-Base spendet Elektronen eine Lewis-Säure. Obwohl BH3und PPh3nicht unbedingt eine Säure und Base, bzw. gelten würde mit anderen Säure-Base-Theorien, prognostiziert Lewis-Säure-Basen-Theorie...
The Lewis acid centers of NFH3+ and NF4+ were analyzed and the MP2/6-311++G(d,p) calculations were performed for complexes of these cations with HCN molecule. The HCN molecule may be linked through the N-atom with the H, F or N centre of cation, i.e. through the hydrogen bond ...
The nitro groups of high explosives may act as weak Lewis-base donors to silacycles. This provides a donor–acceptor interaction that may be crucial for orienting the explosive analyte in the polymer film to provide an efficient pathway for inner-sphere electron transfer during the electron-...
High ortho-selectivity was achieved by a Lewis acid–base interaction between a boryl group of the ligand and a sulfur atom of the substrate. This is the first example of a catalytic and regioselective CH transformation controlled by a Lewis acid–base interaction between a ligand and a ...

Lewis acid-base pairsWe have quantum chemically investigated the bonding between archetypical Lewis acids and bases. Our state﹐f‐the゛rt computations on the X3BNY3 Lewis pairs have revealed the origin behind the systematic increase in BN bond strength as X and Y are varied from F to Cl, ...
Lewis acid–base interactionOrientationPolarizationWe present our unified Lewis acidbase approach to adhesion and solvation at the liquid-polymer interface. This approach is to complement the original methodologies proposed by Fowkes and by van Oss, Chaudhury and Good (VCG). Intermolecular interactions ...
The simplest Lewis acid plus Lewis base interaction is complexation and this process can be represented using both Lewis theory and FMO theory:Using Lewis theory, electron accountancy and curly arrows, the lone-pair of electrons moves from the Lewis base to the Lewis acid, the electron-pair ...
