Heterogeneous Electrocatalytic CO2 Reduction by Supported Molecular Catalysts Well Dispersed on Electrode Surface

open access: yesChemElectroChem, EarlyView.
This mini review overviews the most recent advances (2020–2024) in heterogeneous electrocatalytic CO2R by well‐dispersed molecular catalysts on electrode surface, mainly focusing on the impacts of efficient molecule‐level dispersion and rational catalyst‐support interactions on electronic properties, multi‐electron transfer kinetics, and overall ...

Regioselectivity in the Thermal Rearrangement of Unsymmetrical 4-Methyl-4H-1,2,4-triazoles to 1-Methyl-1H-1,2,4-triazoles [PDF]

open access: yesMolecules, 2001
The rearrangement of 4-methyl-3,5-diaryl-4H-1,2,4-triazoles to the corresponding 1-methyl-3,5-diaryl-1H-1,2,4-triazoles showed regioselectivity comparable to that observed for the alkylation of 3,5-diaryl-1H-1,2,4-triazoles. This lends support to a proposed mechanism for the rearrangement that involves consecutive nucleophilic displacements steps.

Two reaction routes for the preparation of aromatic polyoxadiazoles and polytriazoles: Syntheses and properties [PDF]

open access: yes, 1994
Two reaction routes for the preparation of aromatic poly-1,3,4-oxadiazoles and poly-1,2,4-triazoles are studied and their influence on the physical properties, i.e., inherent viscosity, glass transition, degradation temperature, and film integrity of the

Development of Water‐Soluble 3‐Nitro‐2‐Pyridinesulfenate for Disulfide Bond Formation of Peptide Under Aqueous Conditions

open access: yesChemistry – A European Journal, EarlyView.
Highly water‐soluble Npy‐sulfenate functions as an efficient oxidizing agent for the formation of disulfide bonds in thiol‐containing peptides. The Npy‐sulfenate can be used to form a disulfide bond with a thiol‐containing peptide produced by thiol‐additive‐free NCL, thereby facilitating the one‐pot synthesis of adrenomedullin.
