Dual‐Function Electrocatalysis: Simultaneous Wastewater Remediation and Hydrogen Evolution—A Comprehensive Review

Carbon Energy, EarlyView.
Replacing the oxygen evolution reaction with the electro‐oxidation of pollutants and waste streams offers an energy‐efficient route for simultaneous hydrogen production and pollutant remediation. This review summarizes the reaction mechanisms, catalyst design principles, and emerging paired‐electrolysis strategies that govern activity, selectivity ...

Microwave-Assisted Synthesis of Tetrahydrocarbazole Linked 1,2-Diazoles in Aqueous-Brønsted Acid Catalytic System

Journal of Chemistry, 2017
A new series of tetrahydrocarbazole coupled 1,2-diazoles 4/5/6(a–o) in moderate to excellent yield was synthesized successfully via multicomponent reaction approach by adopting Michael type-addition of hydrazines on in situ generated α,β-unsaturated ...

Stereochemical Control in the Matteson Reaction

Chemistry – A European Journal, EarlyView.
The Matteson homologation is a highly versatile method for the stereoselective insertion of carbenoids into boronic esters. Through iterative application of the process, complex chiral molecules can be synthesized. The stereoselectivity of the reaction is determined by a chiral diol incorporated in the boronic ester.

Hybrid Macrocyclic Peptides — Synthetic Strategies to Diversify and Cyclize Peptide Libraries in Phage Display Selections

Chemistry – A European Journal, EarlyView.
Hybrid macrocyclic peptides unite genetically encoded peptide libraries with the structural complexity of synthetic small molecules. This Review critically analyzes phage‐compatible cyclization and diversification chemistries, highlights emerging opportunities beyond traditional cysteine‐based approaches, and outlines how future advances may enable the

Bismuth Chalcogenide‐Based Photocatalysts for Nitrogen Reduction: Recent Progress and Prospects

Chemistry – A European Journal, EarlyView.
Bismuth chalcogenides emerge as promising visible‐light photocatalysts for sustainable ammonia synthesis, driven by tunable electronic structures and strong N2 activation. Recent advances reveal how defects, doping and heterojunction design synergistically enhance charge separation and reactivity. Key challenges and future directions highlight pathways

Desymmetrization of meso-Bicyclic Hydrazines by Rhodium-Catalyzed Enantioselective Hydroformylation

, 2008
International audienceAn asymmetric hydroformylation of three meso-bicyclic hy-drazines followed by the reduction of the formyl product afforded the corresponding desymmetrized optically enriched hydroxymethyl hydrazines (up to 77.5 % ee)

Expanding the Scope of Indium in Frustrated Lewis Pair Chemistry

Chemistry – A European Journal, EarlyView.
All good things come in threes: The pyridine‐“protected” FLP tBu2InCH2PtBu2·Py shows three different kinds of reactivity: Besides “typical” FLP activity, it prefers formation of the “soft” isomers for substrates with multiple sites for FLP attack, but reacts with SO2 as a “masked” In/C FLP by insertion into the In─C bond.

Derivatives of phenyl tribromomethyl sulfone as novel compounds with potential pesticidal activity

Beilstein Journal of Organic Chemistry, 2012
A halogenmethylsulfonyl moiety is incorporated in numerous active herbicides and fungicides. The synthesis of tribromomethyl phenyl sulfone derivatives as novel potential pesticides is reported. The title sulfone was obtained by following three different

Oxidized Phenyl−Substituted Sesquibicyclic Hydrazines

, 1995
The effect of a− and P−phenyl substituents on the neutral, +1, and +2 oxidation states of bis−N,N'− bicyclic hydrazines 1 and 2 is discussed. An a−phenyl substituent on 2 makes first electron removal 1.8 kcal/mol more difficult, but second electron ...
