Free nilpotent minumim algebras
(Wiley VCH Verlag, 2006-05)
In the present paper we give a description of the free algebra over an arbitrary set of generators in the variety of nilpotent minimum algebras. Such description is given in terms of a weak Boolean product of directly ...
On approximation properties in Lipschitz-free spaces over groups
(Wiley, 2022-04-05)
We study Lipschitz-free spaces over compact and uniformly discrete metric spaces enjoying certain high regularity properties - having group structure with left-invariant metric. Using methods of harmonic analysis we show ...
Catalyst- and solvent-free hydrophosphination and multicomponent hydrothiophosphination of alkenes and alkynes
(Royal Society of Chemistry, 2016-05-26)
The hydrophosphination of carbon-carbon multiple bonds has been generally performed under acid, base or metal catalysis in different solvents. Herein, alkyl and alkenyl tertiary phosphines are obtained by the addition of ...
Antioxidant capacity of diethyldithiocarbamate in a metal independent lipid peroxidative process
(1989)
2,2′-Azobis-[2-amidinopropane] initiated lipid peroxidation of egg yolk phosphatydil choline liposomes was measured by oxygen uptake and the emitted visible luminescence. Lipid peroxidation involved a chain process (kinetic ...
Immobilized and free cells of geotrichum candidum for asymmetric reduction of ketones: Stability and recyclability
(2018-08-27)
Marine-derived fungus Geotrichum candidum AS 2.361 was previously reported by our group as an active strain for the enantioselective reduction of ketones. Although some other Geotrichum strains were also found from the ...
Solvent-free multicomponent synthesis of 2-arylpyridines using p-sulfonic acid calix[6]arene as a reusable catalyst
(Comptes Rendus Chimie, 2018)
