Stephan of the University of Toronto and his coworkers took the concept of Lewis acid-base pairs to a new level when they devised a chemical construct known as a frustrated Lewis pair. Lewis acid-base pairs are common in chemistry: An electron-deficient Lewis acid readily shares a Lewis ...
Their steric demands preclude formation of simple Lewis acid-base adducts, allowing for the subsequent actions of both Lewis acids and bases on other molecules.This concept of FLPs has been extended to demonstrate new reactivity,ultimately leading to new approaches in catalysis.The advent of this ...
(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 ...
Based on this meaning, we suggest a Chinese translation for this :frustrated Lewis pair, Lewis acid�base adduct, steric hindrance自Stephan等[1]2006年首次提出frustrated Lewis pairs(FLP)类物质用于可逆非金属催化加氢反应以来,该概念受到了国内外化学人士的广泛关注。Berke等[2]最近发表了一篇FLP活化端炔...
Surface frustrated Lewis pairs (SFLPs) have been implicated in the gas‐phase heterogeneous (photo)catalytic hydrogenation of CO2 to CO and CH3OH by In2O3?x(OH)y. A key step in the reaction pathway is envisioned to be the heterolysis of H2 on a proximal Lewis acid–Lewis base pair, ...

Frustrated Lewis pairs (FLP), a couple comprising a sterically encumbered Lewis acid and Lewis base, can offer latent reactivity for activating inert gas molecules. However, their use as a platform for fabricating gas‐responsive materials has not yet developed. Merging the FLP concept with ...
Some such systems activate dihydrogen and transfer the resulting proton/hydride pair even to some electron-poor alkynes. Eventually, we report on the reaction of our intramolecular ethylene-bridged P/B FLP with nitric oxide (NO). N,B-addition of the P-Lewis base/B-Lewis acid combination is ...
