The family of Lewis acid-base reactions:;(where L denotes representative electron pair donors) was investigated in this context. Relevant heats of reaction and equilibrium constants in buffered aqueous solutions were determined with the aid of thermometric enthalpy titrations and computerized evaluation ...
and spectra of Lewis acid-base adducts or donor-acceptor complexes, nor is it truly a textbook. Rather it is a cross between a retrospective essay and a current review. Its purpose is to explore the potential of the Lewis acid-base concepts as a systematizing tool in chemistry, and to d...
The six types of Lewis acid and four types of Lewis base can be arranged into an interaction matrix that generates 24 types of Lewis acid/base interaction complex and associated reaction chemistry, as discussed in detail on the next page of this webbook....
Inorganicchemistry,Lewisbasesarenucleophiles Becareful: There are only acids, bases, and acid-base complexes in the theory of 1.Lewis acids and bases, and there is no concept of salt; 2., in the theory of acid-base electron, whether a substance belongs to the base, or whether it belongs...

Gilbert Lewis (1875-1946) was an American chemist who discovered the bonding electron pairs, and who the acid and base concepts are named after. He attended Harvard University and taught at Berkley college for 34 years. He helped mold the chemistry program and teachings into one of the best ...
The Lewis theory provides an addendum to the Brønsted theory that only uses proton transfer to define acid-base reactions by incorporating the transfer of a lone pair. Therefore, while all Brønsted–Lowry acids are protic acids, Lewis acids can be protic or aprotic. This is delineated using...

Acids and bases are an important part of organic chemistry. One of the most applicable theories is the Lewis acid/base motif that extends beyond the Brønsted-Lowry definition described in the previous section. Introduction The Brønsted-Lowry acid-base theory is still used extensively, but it...
group on the α-oxygen provide enantiomerically enriched α,β-dihydroxy esters with high syn-diastereoselectivity, whereas the tert-butyldimethylsilyl ketene acetals derived from bulky esters of α-methoxyacetic acid provide enantiomerically enriched α,β-dihydroxy esters with high anti-diastereoselecit...
