Nitrogen modified cobalt catalysts supported on carbon were prepared by pyrolysis of the mixture generated from cobalt(II) acetate in aqueous solution of melamine or waste melamine resins, which are widely used as industrial polymers. The obtained nanostructured materials catalyze the transfer hydrogenation of N-heteroarenes with formic acid in the absence of base. The optimal Co/Melamine2@C-70...
متن کاملA fluorinated dendritic TsDPEN-Ru(II) catalyst for asymmetric transfer hydrogenation of prochiral ketones in aqueous mediaw
Asymmetric transfer hydrogenation (ATH) has been widely used as an efficient and practical method for preparation of optically pure secondary alcohols that are important key intermediates for the synthesis of a large number of pharmaceutical substances. One of the most attractive catalyst system is based on Ru-TsDPEN (TsDPEN= N-(p-tolylsulfonyl)-1,2diphenylethylenediamine) complexes, which was ...
متن کاملAsymmetric transfer hydrogenation of imines and iminiums catalyzed by a water-soluble catalyst in water.
The first asymmetric transfer hydrogenation of cyclic imines and iminiums in water was successfully performed in high yields and enantioselectivities with sodium formate as the hydrogen source and CTAB as an additive catalyzed by a water-soluble and recyclable ruthenium(II) complex of the ligand (R,R)-2.
متن کاملDirect synthesis of formic acid from carbon dioxide by hydrogenation in acidic media
The chemical transformation of carbon dioxide into useful products becomes increasingly important as CO2 levels in the atmosphere continue to rise as a consequence of human activities. In this article we describe the direct hydrogenation of CO2 into formic acid using a homogeneous ruthenium catalyst, in aqueous solution and in dimethyl sulphoxide (DMSO), without any additives. In water, at 40 °...
