Creation through Immobilization: A New Family of High Performance Heterogeneous Bifunctional Iminophosphorane (BIMP) Superbase Organocatalysts was written by Goldys, Anna M.;Nunez, Marta G.;Dixon, Darren J.. And the article was included in Organic Letters in 2014.SDS of cas: 10203-58-4 This article mentions the following:
An immobilized chiral bifunctional iminophosphorane superbase organocatalyst I has been developed and applied in a range of challenging enantioselective reactions. A unique feature of this novel catalytic system is that the final step creation of the iminophosphorane occurs at the point of immobilization. The utility of the immobilized catalyst system was demonstrated in the nitro-Mannich reaction of ketimines as well as the conjugate addition of high pKa 1,3-dicarbonyl pro-nucleophiles to nitrostyrene. Catalyst recycling was also demonstrated. In the experiment, the researchers used many compounds, for example, Diethyl isobutylmalonate (cas: 10203-58-4SDS of cas: 10203-58-4).
Diethyl isobutylmalonate (cas: 10203-58-4) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Esterification is the general name for a chemical reaction in which two reactants (typically an alcohol and an acid) form an ester as the reaction product. Esters are common in organic chemistry and biological materials.SDS of cas: 10203-58-4
