Intramolecular Nickel‐Catalyzed Reductive Coupling: Enantioselective Synthesis of Tetrahydroisoquinolines and Related Heterocycles

open access: yesAngewandte Chemie, EarlyView.
The successful extension of the nickel‐catalyzed asymmetric coupling of polarized 1,3‐dienes with aldehydes to an intramolecular setting opens an efficient new entry into hydroxylated N‐heterocyclic compounds, most notably valuable tetrahydroisoquinolines.

Photochemical Reaction Discovery Enabled by the Dynamic Speciation of Copper Complexes

open access: yesAngewandte Chemie, EarlyView.
A strategy for accelerated photochemical reaction discovery is reported that harnesses the dynamic speciation of copper complexes, driven by their labile metal–ligand bonds. This platform simplifies reaction screening by combining an earth‐abundant copper(II) salt with commercially available ligands, which reversibly generate multiple catalytic species

Pilarização de esmectita brasileira para fins catalíticos. Emprego de argila pilarizada na alquilação de benzeno com 1-dodeceno Pillarization of Brazilian smectite for the catalytic of purpose. Use of pillared clay in the alkylation of benzene with 1-dodecene

open access: yesQuímica Nova, 2000
Al-pillared clay was prepared with a Brazilian bentonite from the Campina Grande region (Paraíba, BRAZIL). It was intercalated at 298 K, during 48 hours, with a solution containing [Al3+] = 0.10 mol/L and molar ratio OH/Al = 2.0 prepared at 333 K, and ...

Thermodynamics of Chemical Hydrogen Storage: Are Sterically Hindered and Overcrowded Molecules More Effective?

open access: yesApplied Sciences, 2023
Homocyclic aromatics with different degrees of alkylation have been investigated so far as Liquid Organic Hydrogen Carriers (LOHC). A low enthalpy of reaction for the dehydrogenation reaction is generally considered beneficial.

Carbon‐Encapsulated Gemini Ionic Liquid as Advanced Bromine Hosts for High‐Performance Zn–Br2 Batteries

open access: yesAngewandte Chemie, EarlyView.
Rapid self‐discharge limits the practical deployment of Zn–Br2 batteries. Herein, a gemini ionic liquid featuring dual bromine‐binding sites and an aromatic linker is confined within porous carbon electrodes. The ionic liquid simultaneously complexes bromine species and interacts strongly with the carbon matrix, enabling efficient bromine retention ...
