Catalytic reductive desymmetrization of malonic esters

Nature Chemistry, 2021
Desymmetrization of fully substituted carbons with a pair of enantiotopic functional groups is a practical strategy for the synthesis of quaternary stereocentres, as it divides the tasks of enantioselection and C-C bond formation. The use of disubstituted malonic esters as the substrate of desymmetrization is particularly attractive, given their easy ...

Catalytic reduction of nitrate with Pd-In2O3

Environmental Science and Pollution Research, 2020
This work presents a novel catalyst preparation method and the optimization of operation conditions for an effective NO3- conversion with a high selectivity and stability that guarantee water quality for human consumption. Catalytic reduction of NO3- and NO2- was carried out with Pd supported on In2O3 under mild operation conditions (25 °C, 1 atm) with

Catalytic Reductive Vinylidene Transfer Reactions

Journal of the American Chemical Society, 2017
Methylenecyclopropanes are important synthetic intermediates that possess strain energies exceeding those of saturated cyclopropanes by >10 kcal/mol. This report describes a catalytic reductive methylenecyclopropanation reaction of simple olefins, utilizing 1,1-dichloroalkenes as vinylidene precursors.

Catalytic reduction of 2-nitroaniline: a review

Environmental Science and Pollution Research, 2017
2-nitroaniline (2-NA) is highly toxic and environmental contaminant. It is reduced to less toxic and environmental benign product o-phenylenediamine by using different reducing agents like sodium borohydride, potassium borohydride, or hydrazine hydrate in the presence of various catalytic systems.

Catalytic Azide Reduction in Biological Environments

ChemBioChem, 2012
AbstractIn the quest for the identification of catalytic transformations to be used in chemical biology and medicinal chemistry, we identified iron(III) meso‐tetraarylporphines as efficient catalysts for the reduction of aromatic azides to their amines.

Catalytic Deoxydehydration of Glycols with Alcohol Reductants

ChemSusChem, 2013
Top shelf dehydration: Ammonium perrhenate catalysts combined with benzylic alcohol reductants are used for the efficient deoxydehydration of glycols to olefins. The olefin and aldehyde products can be easily separated and isolated. It is also demonstrated that the catalyst can be recovered and reused because of its low solubility in aromatic solvents.
