Selective N‐Functionalization of Pyrazoles

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
This review traces the evolution of regioselective N‐functionalization strategies for pyrazoles, a key class of nitrogen heterocycles widely used in medicinal chemistry. Due to rapid tautomerism, N‐functionalization often lacks selectivity, leading to poor and unpredictable regioisomeric outcomes.

A Synthetic Route to Quaternary Pyridinium Salt-Functionalized Silsesquioxanes

open access: yesInternational Journal of Polymer Science, 2012
A synthetic route to potentially biocidal silsesquioxanes functionalized by quaternary pyridinium functionalities has been developed. N-Alkylation reactions of the precursor compounds 4-(2-(trimethoxysilyl)ethyl)-pyridine (5) and 4-(2-trichloro ...

Ionic liquids: structure–toxicity relationships, predictive toxicology, and sustainable design

open access: yesJournal of Chemical Technology &Biotechnology, EarlyView.
Abstract Ionic liquids (ILs) have often been described as green alternatives to conventional solvents because of their negligible vapor pressure and highly tunable properties. However, low volatility does not necessarily translate into environmental safety, as their biological and ecological effects are strongly influenced by molecular structure.

Gold(I)‐Catalyzed Annulation of Pyridines Containing Alkyne: Synthesis of N‐Alkenyl Pyridonyl Azides via Rearrangement

open access: yesJournal of Heterocyclic Chemistry, EarlyView.
One‐pot gold(I)‐catalysts synthesis was developed in order to prepare N‐alkenyl 2‐pyridonyl azides. This method provides a series of N‐alkenyl 2‐pyridonyl azides in moderate to excellent yields (up to 94%). ABSTRACT A novel strategy, involving the preparation of gold‐catalyzed cyclization salts and the rearrangement of these salts in the presence of ...

Cross‐Scale Engineering of Single‐Atom Catalysts from Local Planar Coordination to Spatial Architectures

open access: yesSmall, EarlyView.
This Review presents a cross‐scale framework for single‐atom catalysts, spanning in‐plane and out‐of‐plane coordination; primary coordination, secondary‐sphere interactions, through‐space microenvironments and support interfaces; individual sites and macroscopic architectures; and static design and directed dynamic reconstruction.
