The Wolff-Kishner Reaction at Atmospheric Pressure

Gold nanoparticles supported on TiO2–Ni as catalysts for hydrogen purification via water–gas shift reaction

“…16 On the other hand, there is evidence that nickel oxide can act as reducible support and has a good performance in many reactions such as catalytic hydrogenation, Wolff-Kishner and Clemmensen reduction, methanation by Fisher Tropsch, among others. [17][18][19] Also, Sreethawong et al 20 reported synthesis of mesoporous TiO 2 -supported NiO photocatalyst by single step sol-gel process for photocatalytic H 2 -production from methanol aqueous solution. Jing et al 21 investigated the fabrication of Ni-doped mesoporous TiO 2 and its photocatalytic activity for hydrogen evolution in methanol aqueous solution.…”

Syntheses of three stable isotope‐labeled ethylcyclopropanes

“…34.6°C), an excellent solvent for preparing CH 3 MgI, was not appropriate for dealing with an ethereal solution of ethylcyclopropane (b.p. 36.2°C) 10. The same conclusion was reinforced through experiments with capillary and preparative GC trials with ether and 1 .…”

Azeotropes as Powerful Tool for Waste Minimization in Industry and Chemical Processes

“…The Wolff−Kishner reduction allows for the obtainment of methylene groups from carbonylic functionalities making this reaction extremely useful in organic chemistry and several modifications have been largely applied over the years. Glycols were generally employed to allow an increase in the reaction temperature and facilitate the removal of water [ 59 , 60 , 61 ] formed during the reaction, and also removal of excess of hydrazine hydrate [ 61 ]. However, due to the extreme conditions of these conditions, further improvements were desirable.…”
