In ionic liqs. (ILs), the activation of a ruthenium(II) catalyst precursor occurs via an unexpected mechanism, which is different from the activation mechanism that takes place in water. The effectiveness of a biphasic catalytic hydrogenation reaction usin ...
Hydrogenation of 2-butyne-1,4-diol catalyzed by Pd nanoparticles on activated carbon fibers (ACFs) was studied. The ACF support in the form of woven fabrics provides the basis for structured catalytic fixed beds. In the present study, this catalyst was int ...
Hydrogenation of C60 at 2 GPa and 723-823 K was performed with thermal decompn. of LiAlH4 as a hydrogen source. Anal. of hydrogenation products showed that the method can produce not only C60H36, but also hydrofullerides C60Hx with 44 < x < 52. Unlike othe ...
The catalytic activity of the iridium complexes involved in methanol carbonylation is significantly enhanced when the carbonyliodoplatinum dimer [PtI2(CO)]2 (10') is added to the reaction mixt. Under CO this complex readily affords th ...
The phosphido-substituted triruthenium cluster Ru-3(CO)(9)(mu-H)(mu-PPh2) is shown to react with H-2 to form the trihydride cluster Ru-3(CO)(9)(H)(mu-H)(2)(mu-PPh2), which undergoes a number of re-arrangement reactions on heating to yield other phosphido-s ...
Many low oxidation state transition metal (carbonyl) clusters are salts and are highly soluble in ionic liquids. Since many are also effective catalysts/precatalysts for hydrogenation reactions, we have conducted a catalytic study of these compounds in ion ...
NOVELTY - A 2-butene-1,4-diol is prepared by hydrogenating 2-butyne-1,4-diol in the presence of a structured catalyst and in the absence of a solvent. USE - For preparing 2-butene-2,4-diol that is an important industrial intermediate in the preparation of ...
This work covers homogeneous and biphasic catalysis in ionic liquids and water. The work presented herein is divided into two major parts: catalytic hydrogenation and catalytic hydroformylation. The first part also serves as an introduction to catalysis in ...
Development of selective oxidation catalysts is a major concern of modern chemical industry. Among several systems, VTi-oxide based catalysts showed the most promising and versatile, able to catalyse key reactions like oxidation of o-xylene to phtalic anhy ...
