This Perspective highlights recent developments in methane conversion into different hydrocarbons and C<sub>1</sub>-oxygenates. Our analysis identified possible directions for further research to bring the above approaches a commercial level.
Abstract The production of primary benzylic and aliphatic amines, which represent essential feedstocks key intermediates for valuable chemicals, life science molecules materials, is central importance. Here, we report the synthesis this class amines starting from carbonyl compounds ammonia by Ru-catalyzed reductive amination using H 2 . Key to success use a simple RuCl (PPh 3 ) catalyst that empowers >90 various linear branched benzylic, heterocyclic, under industrially viable scalable...
Supported bimetallic nanoparticles (SBN) are extensively used as efficient redox catalysts. This kind of catalysis particularly using SBN has attracted immense research interest compared to their parent metals due unique physico-chemical properties. The primary objective this contribution is provide comprehensive overview about and application promising present review contains four sections in total. Section 1 starts with a general introduction, recent progress, brief summary the catalysts...
We report the synthesis of <italic>in situ</italic> generated cobalt nanoparticles from molecularly defined complexes as efficient and selective catalysts for reductive amination reactions.
Nanoscale Fe<sub>2</sub>O<sub>3</sub>-catalyzed environmentally benign synthesis of nitriles and amides has been performed from easily accessible aldehydes ammonia using O<sub>2</sub>.
The synthesis of amides is a key technology for the preparation fine and bulk chemicals in industry, as well manufacture plethora daily life products. Furthermore, it constitutes central bond-forming methodology organic provides basis numerous biomolecules. Here, we present robust amide compared to traditional amidation reactions: reductive esters with nitro compounds under additives-free conditions. In presence specific heterogeneous nickel-based catalyst wide range bearing different...
A series of V2O5/Al2O3 catalysts with fixed V2O5 content (10 wt %) but varying Al2O3 supports were prepared by impregnation technique and tested for the oxidative dehydrogenation ethane (ODHE) to ethylene in a bed quartz reactor temperature range from 500 600 °C. The nature alumina support applied had significant influence on catalytic performance. Among all investigated, high surface area γ-Al2O3 (200–300 m2/g) supported catalyst showed best performance ODHE selectivity ca. 45–50%. This...
Ammoxidation of p-nitrotoluene (PNT) to p-nitrobenzonitrile (PNB) has been carried out over some bulk and supported vanadium phosphate (VPO) catalysts also on V2O5 for the first time. The solid PNT was successfully metered catalyst bed using a saturator by maintaining temperature in above melting point with simultaneous bubbling known amount nitrogen gas as carrier vapours. observed undergo kind thermal decomposition at temperatures higher than 623 K even absence evidenced from blank tests....
Abstract N ‐Methyl‐ and ‐alkylamines represent important fine bulk chemicals that are extensively used in both academic research industrial production. Notably, these structural motifs found a large number of life‐science molecules play vital roles regulating their activities. Therefore, the development convenient cost‐effective methods for synthesis functionalization amines by using earth‐abundant metal‐based catalysts is scientific interest. In this regard, herein we report an expedient...
Abstract Use of ZrO 2 /SiO as a solid acid catalyst in the ring‐opening biobased γ‐valerolactone with methanol gas phase leads to mixtures methyl 2‐, 3‐, and 4‐pentenoate (MP) over 95 % selectivity, containing surprising 81 M4P. This process allows application selective hydroformylation this mixture convert M4P into 5‐formyl‐valerate (M5FV) 90 selectivity. The other isomers remain unreacted. Reductive amination M5FV ring‐closure ϵ ‐caprolactam excellent yield had been reported before....
A high-throughput screening exercise testing 60 different catalysts resulted in 5 wt % Pt on sulfided carbon as the best catalyst conversion of bio-based methyl levulinate (ML) to vinyl ketone (MVK) a gas-phase continuous process. Up 18% yield MVK was obtained, but fast deactivation observed. For better understanding reaction mechanism, potential intermediates [α-angelica lactone (α-AL), γ-valerolactone, ethyl (MEK), and levulinic acid (LA)] were also fed starting materials under same...
Tuning the surface composition of metal vanadates using different cations leads to development a new class highly effective catalysts tested in ammoxidation 2-methylpyrazine. Especially, an enrichment V near-surface region is beneficial for improved selectivity. With this approach, knowledge based optimisation was possible first time, which indeed led efficient novel LaVOx with high yield 2-cyanopyrazine (≥85%) and extremely space-time-yields (ca. 525 g−1CP kg−1cat h−1).
During catalytic methane oxidation V/Ti-SBA-15 showed an improved selectivity towards formaldehyde over all conversions compared to V/SBA-15.
