Unimolecular Solvolyses in Ionic Liquid: Alcohol Dual Solvent Systems

open access: yesMolecules, 2016
A study was undertaken of the solvolysis of pivaloyl triflate in a variety of ionic liquid:alcohol solvent mixtures. The solvolysis is a kΔ process (i.e., a process in which ionization occurs with rearrangement), and the resulting rearranged carbocation ...

Harnessing Random Polymers as Chemoselective Catalysts With Structural Adaptability: Epoxidation of Olefinic Quaternary Ammonium Salts via Charge Recognition

open access: yesChemistry – A European Journal, Volume 32, Issue 27, 17 July 2026.
The development of chemoselective catalysts that operate across structurally diverse substrates remains a long‐standing challenge. Here, we demonstrate that a random heteropolymer bearing carboxylic acid and urea residues functions as a general epoxidation catalyst for olefinic quaternary ammonium salts.

Aqueous DMSO Mediated Conversion of (2-(Arylsulfonyl)vinyl)iodonium Salts to Aldehydes and Vinyl Chlorides

open access: yesMolecules, 2016
Vinyl(aryl)iodonium salts are useful compounds in organic synthesis but they are under-utilized and their chemistry is under-developed. Herein is described the solvolysis of some vinyl(phenyl)iodonium salts, bearing an arylsulfonyl group, in aqueous DMSO

Monosubstituted N‐Arylhydroxylamine Chemistry: Integrating Contemporary Synthetic Approaches for the Efficient Construction of Diverse Heterocyclic Scaffolds

open access: yesChemistry – A European Journal, Volume 32, Issue 26, 11 July 2026.
Monosubstituted N‐arylhydroxylamines represent a unique subclass of hydroxylamines that act as pivotal intermediates in redox transformations and as versatile platforms for further synthetic transformations. They serve as key building blocks in the synthesis of architecturally complex heterocycles and other valuable organic compounds.
