Colloidal Nanocrystals as Precursors and Intermediates in Solid State Reactions for Multinary Oxide Nanomaterials
Raffaella Buonsanti, Anna Loiudice, Valeria Mantella
Polyelemental compounds with dimensions in the nanosized regime are desirable in a large variety of applications, yet their synthesis remains a general challenge in chemistry. One of the major bottlenecks to obtaining multinary systems is the complexity of ...
AMER CHEMICAL SOC2021Catalyst Proximity-Induced Functionalization of h-BN with Quat Derivatives
Magalí Alejandra Lingenfelder, Gabriele Tocci, Bart Willem Stel, Huanyao Cun
Inert single-layer boron nitride (h-BN) grown on a catalytic metal may be functionalized with quaternary ammonium compounds (quats) that are widely used as nonreactive electrolytes. We observe that the quat treatment, which facilitates the electrochemical ...
2019Nickamine and Analogous Nickel Pincer Catalysts for Cross-Coupling of Alkyl Halides and Hydrosilylation of Alkenes
Xile Hu, Zhikun Zhang, Renyi Shi
CONSPECTUS: Ligand development plays an essential role in the advance of homogeneous catalysis. Tridentate, meridionally coordinating ligands, commonly termed pincer ligands, have been established as a privileged class of ligands in catalysis because they ...
AMER CHEMICAL SOC2019Intricacies of Cation-Anion Combinations in Imidazolium Salt-Catalyzed Cycloaddition of CO2 Into Epoxides
Paul Joseph Dyson, Gabor Laurenczy, Felix Daniel Bobbink, Florent Menoud, Martin Hulla, Dmitry Vasilyev, Sami Manoubi Armand Chamam
The cycloaddition of CO2 into epoxides catalyzed by imidazolium and related salts continues to attract attention due to the industrial importance of the cyclic carbonate products. The mechanism of the imidazolium-catalyzed transformation has been proposed ...
2018Chemical Distribution of Multiple Cation (Rb+, Cs+, MA(+), and FA(+)) Perovskite Materials by Photoelectron Spectroscopy
Ulf Anders Hagfeldt, Michael Saliba, Juan-Pablo Correa-Baena, Silver Hamill Turren Cruz
Lead-based mixed perovskite materials have emerged in the last couple of years as promising photovoltaic materials. Recently, it was shown that improved material stability can be achieved by incorporating small amounts of inorganic cations (Cs+ and Rb+), p ...
American Chemical Society2017Phosphonium and Ammonium Ionic Liquids with Aromatic Anions: Synthesis, Properties, and Platinum Extraction
Several hydrophobic long-chain quaternary ammonium and phosphonium ionic liquids (ILs) with functionalized aromatic anions were prepared following a metathesis route using tricaprylmethylammonium chloride (Aliquat 336) and trihexyl(tetradecyl) phosphonium ...
2010Ultrafast Optical and X-ray Absorption Studies of Solvation Dynamics
Solvation dynamics, the process of solvent reorganization upon electronic excitation of a solute, is central to our understanding chemical reactions in liquid phase. Ultrafast optical studies of solvation dynamics have so far been carried out on polyatomic ...
EPFL2010Phosphodiester Cleavage in Ribonuclease H Occurs via an Associative Two-Metal-Aided Catalytic Mechanism
Ribonuclease H (RNase H) belongs to the nucleotidyl-transferase (NT) superfamily and hydrolyzes the phosphodiester linkages that form the backbone of the RNA strand in RNA x DNA hybrids. This enzyme is implicated in replication initiation and DNA topology ...
2008A theoretical study on the formation of EX4+ and E2X5+ (E = P, As; X = Br, I) from Ag+ and EX3/X2
The mechanism and the thermodn. of the formation of EX2+, EX4+ and E2X5+ (E = As, P; X = Br, I) was carefully analyzed with MP2/TZVPP calcns. and inclusion of entropy and solvation effects (COSMO model approximating CH2Cl2). Thus, as likely intermediates t ...
