The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: 2,5-Diphenyloxazole(SMILESS: C1(C2=CC=CC=C2)=NC=C(C3=CC=CC=C3)O1,cas:92-71-7) is researched.Recommanded Product: 111-18-2. The article 《One-pot dual catalysis for the hydrogenation of heteroarenes and arenes》 in relation to this compound, is published in Catalysis Science & Technology. Let’s take a look at the latest research on this compound (cas:92-71-7).
A simple dinuclear monohydrido bridged ruthenium complex [{(η6-p-cymene)RuCl}2(μ-H-μ-Cl)] acted as an efficient and selective catalyst for the hydrogenation of various heteroarenes and arenes. The nature of the catalytically active species was investigated using a combination of techniques including in situ reaction monitoring, kinetic studies, quant. poisoning experiments and electron microscopy, evidencing a dual reactivity. The results suggested that the hydrogenation of heteroarenes proceeded via mol. catalysis. In particular, monitoring the reaction progress by NMR spectroscopy indicated that [{(η6-p-cymene)RuCl}2(μ-H-μ-Cl)] was transformed into monomeric ruthenium intermediates, which upon subsequent activation of dihydrogen and hydride transfer accomplish the hydrogenation of heteroarenes under homogeneous conditions. In contrast, carbocyclic aryl motifs were hydrogenated via a heterogeneous pathway, by in situ generated ruthenium nanoparticles. Remarkably, these hydrogenation reactions could be performed using mol. hydrogen under solvent-free conditions or with 1,4-dioxane, and thus gave access to a broad range of saturated heterocycles such as 1,2,3,4-tetrahydroquinoline and carbocycles such as perhydro-9-anthracenemethanol while generating no waste.
