The electrocatalytic cleavage of carbon-halide bonds on Ag and Au in protic solvents [PDF]
, 2011 In the last years we have showed in detail how the electrocatalytic cleavage of carbon-halide bonds is modulated by (a) the stepwise or concerted nature of the DET mechanism, (as a function of the electrode surface, of the nature of the halogen atom, and

Protic N‐Heterocyclic Carbene Ligands in Ruthenium‐Catalyzed Transfer Hydrogenation
Helvetica Chimica Acta, EarlyView.The activity of ruthenium transfer hydrogenation catalysts is strongly influenced by the number of protic units in the N‐heterocyclic carbene ligand. Doubly protic NH, NH ligands induce slower activity than mono‐protic NH, NMe ligands, while NMe, NMe ligands display the highest activity, suggesting metal‐ligand cooperativity is not beneficial for these

The electronic origin of the ground state spectral features and excited state deactivation in cycloalkanones: the role of intermolecular H-bonding in neat and binary mixtures of solvents [PDF]
, 2019 In this study, a D-A cycloalkanone (K1) has been investigated by steady state absorption and fluorescence in neat solvents and in three binary mixtures of nonpolar aprotic/polar protic, polar aprotic/polar protic, and polar protic/polar protic solvents ...

Journal of the Chinese Chemical Society, EarlyView.A modular cascade reaction of epoxy carbamates with diverse thiols provides efficient access to C5 sulfide‐functionalized oxazolidinones. Intermolecular nucleophilic epoxide ring opening followed by intramolecular acyl substitution enables simultaneous sulfur installation and oxazolidinone formation.

Effect of solvents having different dielectric constants on reactivity: a conceptual DFT approach
, 2010 Conceptual density functional theory is exploited to understand the reactivity in a medium of solvents with increasing dielectric constants. Aprotic as well as protic solvents are used for this study.

Journal of Heterocyclic Chemistry, EarlyView.A robust method for synthesizing substituted oxadiazepines and related heterocycles via intramolecular SNAr is detailed. Under mild conditions, this methodology has been leveraged to afford products of varying electronic and aryl nature in up to 99% yields.

Protic Poly(Diallylammonium Sulfonate)s: Toward Water‐Processable Fluorine‐Free Ionic Materials
Macromolecular Rapid Communications, EarlyView.A new family of fluorine‐free protic poly(ionic liquids) was synthesized via free‐radical cyclopolymerization of diallylammonium monomers containing sulfonates as counter‐anions. Their properties were found to depend on both cation and anion structure, showing thermal stability up to 300°C, glass transition temperatures between 20°C and 52°C, ionic ...
