Treatment of a DMA solution of anilide 1 with a catalytic amount of palladium acetate (0.025 equiv) and XPhos (0.05 equiv) in the presence of potassium carbonate (2.0 equiv) at 100 C afforded dihydroquinolin-2-ones spiro-fused to dihydrofuranyl, indolinyl, ...
In recent years, a strong emphasis in research towards creating sustainable and environmental friendly chemical processes has propelled the development of novel types of catalytic systems that combine advantages from homogeneous and heterogeneous processes ...
Supported metal catalysts are important from both an industrial and a scientific point of view. They are used, amongst others, in large-scale processes such as catalytic reforming, hydrotreating, polymerization reactions and hydrogenations. Often, these ca ...
The relationship between catalytic response and properties of the active phase is difficult to establish in classical heterogeneous catalysis due to the number of variables that can affect catalytic performance. Ultrahigh-vacuum surface methods applied to ...
This review describes some of the fascinating advances in the field of rhodium nanoparticle (NP) catalysis that have emerged in recent years. The examples described are categorized according to the research approach applied, involving either direct enginee ...
Traditionally, the search for active and selective catalysts involved a rather tedious "hit-and-miss" approach in which hundreds, if not thousands catalysts were tested until the optimal substance was identified. With the advancing theoretical understandin ...
A highly efficient iron-catalyzed production of 5-hydroxymethylfurfural (HMF) from sugar is reported. The dehydration of fructose and sucrose has been studied in the presence of different iron salts and co-catalysts. As a result, it was found that fructose ...
Pd nanoparticles (NPs) with a small size and narrow size distribution were prepared from the decomposition of Pd(OAc)(2) in a series of hydroxyl-functionalized ionic liquids (ILs) comprising the 1-(2'-hydroxylethyl)-3-methylimidazolium cation and various a ...
We combine low-temperature scanning tunneling microscopy and measurements of the catalytic activity to establish a structure-reactivity correlation for the CO oxidation on Pt nanoclusters on rutile TiO2(110)-(1 x 1). Annealing of the clusters to 1100 K lea ...
Palladium nanohexagons were prepared using a seed-mediated method. Their catalytic performance in 2-methyl-3-butyn-2-ol hydrogenation was compared to the one of monodispersed Pd nanospheres. Quantitative correlations between initial turnover frequencies (T ...
