Synthesis of 1-Substituted 1H-1,2,3,4-Tetrazoles Using Biosynthesized Ag/Sodium Borosilicate Nanocomposite

open access: yesACS Omega, 2019
An expedient solvent-free methodology has been developed to produce 1-substituted 1H-1,2,3,4-tetrazoles using sodium borosilicate glass-supported silver nanoparticles (Ag NPs) as a novel heterogeneous catalyst.

T½ Tuning in a Synergistic BODIPY‐Tetrazole Fe(II) Spin‐Crossover‐Photoluminescence System via Co‐Ligand Variation

open access: yesChemistry – A European Journal, EarlyView.
We report a modular spin crossover‐photoluminescence (SCO‐PL) system: heteroleptic, mononuclear Fe(II) coordination compounds bearing equatorial BODIPY fluorophores that exhibit synergistic PL response upon spin state switching. Exchanging apical nitrile co‐ligands tunes electronic and structural properties, giving precise control over the SCO and PL ...

Expedient Discovery of a Metallaphotoredox Cyanomethylation for Synthesizing α‐Aryl Nitriles

open access: yesChemistry – A European Journal, EarlyView.
A metallaphotoredox cyanomethylation reaction has been developed for the synthesis of valuable α‐aryl nitrile intermediates. The methodology was successfully applied to diverse medicinally‐relevant substrates, providing an expedient route to anti‐cancer Senexin compounds, while also removing the need for toxic cyanide reagents. The mechanism was probed

Synthesis and In Vitro Antiproliferative Activity of Novel Androst-5-ene Triazolyl and Tetrazolyl Derivatives

open access: yesMolecules, 2011
A straightforward and reliable method for the regioselective synthesis of steroidal 1,4-disubstituted triazoles and 1,5-disubstituted tetrazoles via copper(I)-catalyzed cycloadditions is reported. Heterocycle moieties were efficiently introduced onto the

New iron tetrazolate frameworks : synthesis temperature effect, thermal behaviour, Mössbauer and magnetic studies [PDF]

open access: yes, 2015
The exploration of the FeF3/FeF2-Hamtetraz-HF system in dimethylformamide by solvothermal synthesis evidences two isostructural 3D hybrid fluoroferrates. They are prepared from the same starting mixture at two different synthesis temperatures: 120 °C for

Push–Pull Ynamines and Push–Pull Ynamides: Synthesis, Structure, Reactivity, and Application

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
Push–pull ynamines and push–pull ynamides, which carry an EWG and an amino or amido group as EDG, are highly interesting classes of EDG‐EWG alkynes that have been intensively studied due to their exceptional reactivity. In this review, the synthesis, structure, reactivity, and application of push–pull ynamines, push–pull ynecarbamates, push–pull ...

Diverse reactivity of maleimides in polymer science and beyond

open access: yesPolymer International, Volume 74, Issue 4, Page 296-306, April 2025.
This mini‐review provides a thorough overview of maleimide chemistry, highlighting its diverse reactivity in polymer and materials science applications. Abstract Maleimides are remarkably versatile functional groups, capable of participating in homo‐ and copolymerizations, Diels–Alder and (photo)cycloadditions, Michael additions, and other reactions ...
