New Cu (I) complexes as catalyst for "click" reaction: An experimental and computational study
In this work, two novel well-defined Cu (I) complexes of a Schiff base ligand are described. For this purpose, N, N '-bis (trans-cinnamaldehyde) ethylenediimine [C20H20N2] (L) and Cu (I) complex of the type [CuC20H20N2)PPh3Cl] (C1) and [Cu(C20H20N2)PPh3Br] ...
WILEY2023Revisiting the Impact of Morphology and Oxidation State of Cu on CO2 Reduction Using Electrochemical Flow Cell
Shaik Mohammed Zakeeruddin, Jing Gao, Dan Ren
Electroreduction of carbon dioxide (CO2) in a flow electrolyzer represents a promising carbon-neutral technology with efficient production of valuable chemicals. In this work, the catalytic performance of polycrystalline copper (Cu), Cu2O-derived copper (O ...
AMER CHEMICAL SOC2022C-C bond activation enabled by dyotropic rearrangement of Pd(iv) species
Qian Wang, Jieping Zhu, Hua Wu, Jian Cao
The weak carbon-metal bond combined with the kinetic inertness of the carbon-carbon bond renders metal-catalysed C-C bond activation to be highly challenging. Most of the reported C-C bond activation methodologies involve strain-releasing cleavage of small ...
NATURE RESEARCH2021Ethynylation of Cysteine Residues: From Peptides to Proteins in Vitro and in Living Cells
Jérôme Waser, Romain Gaëtan Tessier, Charlotte Marie Sornay, Raj Kumar Nandi
Current approaches to introduce terminal alkynes for bioorthogonal reactions into biomolecules still present limitations in terms of either reactivity, selectivity, or adduct stability. We present a method for the ethynylation of cysteine residues based on ...
2020Molecular motor crossing the frontier of classical to quantum tunneling motion
Harald Brune, Roland Widmer, Jan Prinz, Samuel Thomas Stolz
The reliability by which molecular motor proteins convert undirected energy input into directed motion or transport has inspired the design of innumerable artificial molecular motors. We have realized and investigated an artificial molecular motor applying ...
NATL ACAD SCIENCES2020Palladium-Catalyzed Synthesis of Ketenimines from Isocyanides and Synthetic Studies Towards the Total Synthesis of Mersilongine
In the first chapter of this thesis, the development of two new reactions for the synthesis of vinyl ketenimines and alpha-oxo-ketenimines from isocyanides is presented. These palladium-catalyzed transformations both feature an isocyanide insertion / beta- ...
EPFL2019Steam Gasification of Carbonaceous Feedstocks via a 1.5 kWth Hybrid Solar/Autothermal Reactor
Sophia Haussener, Iacopo Guscetti
A continuous method of steam gasification through hybridization of a solar reactor with an autothermal gasification process is proposed and tested. The ability to autothermally gasify a carbonaceous feedstock within a solar reactor enables round-the-clock ...
AMER INST PHYSICS2019Copper-catalyzed remote C(sp3)–H azidation and oxidative trifluoromethylation of benzohydrazides
Qian Wang, Jieping Zhu, Xu Bao
The Hofmann-Löffler-Freytag (HLF) reaction is a prototypical example of radical-based remote functionalization of unactivated C(sp3)–H bond. While 1,5-hydrogen atom transfer (1,5-HAT) of the amidyl radical is thermodynamically favorable and is well-establi ...
Springer2019Mechanism and Kinetics of Propane Dehydrogenation and Cracking over Ga/H-MFI Prepared via Vapor-Phase Exchange of H-MFI with GaCI3
In this study, the mechanism and kinetics of C3H8 dehydrogenation and cracking are examined over Ga/H-MFI catalysts prepared via vapor-phase exchange of H-MFI with GaCl3. The present study demonstrates that GaH cations are the active centers for C3H8 ...
2019Auger-induced charge migration
Novel perspectives of controlling molecular systems have recently arisen from the possibility of generating attosecond pulses in the ultraviolet regime and tailoring electron dynamics in its natural time scale. The cornerstone mechanism is the so-called ch ...
