Selective hydrogenolysis of 5-hydroxymethylfurfural to 5-methylfurfural over Au/TiO2
5-Methylfurfural (MF) is a critical commodity chemical used as food additive and synthetic intermediate. Opening a sustainable route towards highly selective synthesis of MF from 5-hydroxymethylfurfural (HMF) is of great ...
Co-doped hydroxyapatite as photothermal catalyst for selective CO2 hydrogenation
The rational design and in deep understanding of efficient, affordable and stable materials to promote the light-assisted production of fuels and commodity chemicals is very appealing for energy crisis and climate change ...
Water-Soluble Aryl- and Super Aryl-Extended Calix[4]pyrroles
The study of molecular recognition processes in water using biomimetic synthetic receptors provides valuable information for understanding more complex biological processes. In the last decade, our group focused on the use ...
Isolation of a Ru(iv) side-on peroxo intermediate in the water oxidation reaction
Oxygen-containing mononuclear ruthenium species such as ruthenium(III)-hydroxo, ruthenium(IV)-oxo, ruthenium(V)-oxo and ruthenium(IV)-peroxo are invoked as key intermediates in O-O bond formation during Ru catalyzed water ...
Quantification of the P=O···HN hydrogen bond in the binding of creatinine with phosphonate calix[4]pyrroles
We report the results of 1H and 31P NMR titrations of a series of calix[4]pyrrole cavitands with hexyl creatinine in dichloromethane solution. We show that all studied calix[4]pyrrole cavitands form thermodynamically and ...
Aryl-Extended and Super Aryl-Extended Calix[4]pyrroles: Design, Synthesis, and Applications
Proteins exhibit high-binding affinity and selectivity, as well as remarkable catalytic performance. Their binding pockets are hydrophobic but also contain polar and charged groups to contribute to the binding of polar ...
Electro- and Photoinduced Interfacial Charge Transfers in Nanocrystalline Mesoporous TiO2 and TiO2/Iron Porphyrin Sensitized Films under CO2 Reduction Catalysis
Electro- and photochemical CO2 reduction (CO2R) is the quintessence of modern-day sustainable research. We report our studies on the electro- and photoinduced interfacial charge transfer occurring in a nanocrystalline ...
Selective Binding and Isomerization of Oximes in a Self-Assembled Capsule
A series of straight-chain (C7–C13) alkyl-O-methyl aldoximes (R–C(H)═NOMe) were synthesized with various functional groups at the remote ends (alkenes, halogen, −COOH, and NH2). Their isomers about the C═N bond showed ...
Metal-free Multicomponent Strategy for Amidine Synthesis
Amidines are a ubiquitous class of bioactive compounds found in a wide variety of natural products; thus, efficient strategies for their preparation are in great demand. Specifically, their common structural core decorated ...
Comprehensive Mechanistic Scenario for the Cu-Mediated Asymmetric Propargylic Sulfonylation Forging Tertiary Carbon Stereocenters
Metal-catalyzed propargylic transformations represent a powerful tool in organic synthesis to achieve new carbon–carbon and carbon–heteroatom bonds. However, detailed knowledge about the mechanistic intricacies related to ...
