LEWIS ACID-BASE PAIR ASSISTS ENZYME MIMIC.The article informs that a transition-metal complex featuring a ligand with functional appendages has been designed by the researchers of the University of Michigan that mimic the secondary coordination sphere of a metalloenzyme's binding pocket....
Lewis acid-base pairBiomass conversion.Amphoteric YNbO4 was synthesized by the simple coprecipitation using (NH4)3[Nb(O2)4] and Y(NO3)3, and examined as a new solid acid‐base bifunctional catalyst for various reactions including aqueous﹑hase conversion of glucose to lactic acid. After drying...
The role of Lewis acid-base pair sites in ZnO-ZnCr2O4 catalysts for cyclization via dehydrogenative condensation of crude glycerol and 1,2-propanediamine for the synthesis of 2,6-dimethylpyrazine 作者:Vankudoth Krishna; Padmasri A Hari; Sarkari Reema; Velisoju Vijay Kumar; Gutta Naresh; Sathu...

A key step in the reaction pathway is envisioned to be the heterolysis of H2 on a proximal Lewis acid–Lewis base pair, the SFLP, the chemistry of which is described as In???In‐OH + H2→ In‐OH2+???In‐H?. The product of the heterolysis, thought to be a protonated hydroxide ...
(B,N) was successfully synthesized. By precisely controlling the carbonization temperature of a binary mixed ionic liquid, we selectively modified the doping site structure, ultimately constructing a B,N co-doped frustrated Lewis acid-base pair catalyst. This catalyst exhibited remarkable catalytic ...
1. acid-base reaction is a reaction between an acceptor and an electron pair to form a covalent bond between the donor and the electron: Ag+ +2 = NH3 = [Ag (NH3) 2]+ Two The acid substitution reaction acid replaces the acid in the acid-base complex and forms a new acid-base comp...
Although activation of paraffins over the Lewis acid–base pair formed by Ga3+ oxidic cations is more favorable, these species deactivate to less active Ga+ ions. Clustered gallium oxides are also expected to be active for paraffins activation as suggested by a recent infrared study of the ...
A Lewis acid is any substance that has the ability to accept an electron pair from another compound, usually an H+ ion. A Lewis base is any substance that has the ability to donate an electron pair, usually to an OH- ion. Typically, on the Periodic Table of Elements, bases are on th...
Lewis acid-base pair chemistry has been placed on a new level with the discovery that adduct formation between an electron donor (Lewis base) and acceptor ... Niklas,Zwettler,Nadia,... - 《Chemistry》 被引量: 0发表: 2019年 Heterolytic Si?H Bond Cleavage at a Molybdenum‐Oxido‐Based Lew...
