Nitrogen Lewis Acids.
Pogoreltsev A, Tulchinsky Y, Fridman N, Gandelman M. Pogoreltsev A, et al. J Am Chem Soc. 2017 Mar 22;139(11):4062-4067. doi: 10.1021/jacs.6b12360. Epub 2017 Mar 9. J Am Chem Soc. 2017. PMID: 28240551
Although many chemical elements can serve as the central atom of Lewis acids, nitrogen is usually associated with Lewis bases. Here, we report on the first example of robust and modifiable Lewis acids centered on the nitrogen atom, which provide stable and we …

Lewis acid organocatalysts.
Sereda O, Tabassum S, Wilhelm R. Sereda O, et al. Top Curr Chem. 2010;291:349-93. doi: 10.1007/978-3-642-02815-1_17. Top Curr Chem. 2010. PMID: 21494948 Review.
Their application in asymmetric catalysis can be achieved by the addition of enantiopure ligands to these salts. However, not only metal centers can function as Lewis acids. Compounds containing carbenium, silyl or phosphonium cations display Lewis acid catalytic ac …

Lewis histo-blood group system and associated secretory phenotypes.
Henry S, Oriol R, Samuelsson B. Henry S, et al. Vox Sang. 1995;69(3):166-82. doi: 10.1111/j.1423-0410.1995.tb02591.x. Vox Sang. 1995. PMID: 8578728 Review.
The expression of Lewis system antigens is dependent on Lewis and secretor loci. Fucosyltransferases coded by genes at these loci compete and interact with each other and with other transferases to determine an individual's Lewis and secretor phenotype. ...Tw …

Lewis-Base-Induced Disproportionation of a Dialane.
Hofmann A, Lamprecht A, Jiménez-Halla JOC, Tröster T, Dewhurst RD, Lenczyk C, Braunschweig H. Hofmann A, et al. Chemistry. 2018 Aug 9;24(45):11795-11802. doi: 10.1002/chem.201802300. Epub 2018 Jul 18. Chemistry. 2018. PMID: 29920807
The reaction of a pentamethylcyclopentadienyl-substituted dialane with a variety of Lewis bases results in unexpected disproportionation of the dialane into Al(I) and Al(III) species. Use of a transition-metal Lewis base allows for the formation of metal-only Lew …
