TL;DR: In this article, the authors compared the performance of monolayer V2O5 catalysts for the selective reduction of NO with NH3 compared with those of commercial available catalysts containing V and/or W. The experimental reaction stoichiometry can be explained in terms of suitable combinations of these four reactions.

18 Feb 1986TL;DR: In this paper, a catalyst for the selective reduction of nitrogen oxides to nitrogen in the presence of ammonia in the form of composite bodies formed from a mixture of zirconia (5 to 50%), a zeolite (50 to 90%), a bond material (0 to 30%), and, optionally, a promoter selected from oxides of vanadium and copper in the amount of at least 0.1% by weight.

TL;DR: In this article, the reduction of carbon-carbon double bonds can be achieved with either NiCRA or NiCRASi (nickel containing complex reducing agent activated by Me 3 SiCl).

TL;DR: Pd on carbon increases the reactivity of the system RuCl 2 (PPh 3 ) 3 /HCOOH/Et 3 N and induces selective reduction of nitroaromatic compounds which is faster than that of olefins or haloaromatic derivatives.
14 citations
TL;DR: In this paper, the selective reduction of imines with the diborane-methanol system was investigated, and the system reduced imines quantitatively, and other functional groups tested were unaffected.

21 Oct 1986TL;DR: In this article, a catalyst for the selective reduction of nitrogen oxides to nitrogen in the presence of ammonia in the form of composite bodies formed from a mixture of anatase (5 to 40% by weight), a zeolite (50 to 90%), a bond material (0 to 30%), and, optionally, a promoter which is an oxide of vanadium, molybdenum, or copper, in the amount of at least 0.1 % by weight.

TL;DR: In this article, simple dithiols-ferrous chloride or lipoamide-fricrous chloride were found to be effective catalysts for the selective reduction of substituted alkynes to alkenes with sodium borohydride presumably by forming active Dithiol-Fe(II) complexes.
