Carboxylate–Probase Catalyzed Favorskii Reaction

Chemistry – A European Journal, EarlyView.
Stronger together: A combination of a carboxylate catalyst and a silylating agent generates a stronger base catalyst for a metal‐free catalytic addition of alkynes to aldehydes and ketones under chemoselective, O‐silylative conditions. The reaction is proposed to proceed via quaternary ammonium (Q+) cation – acetylide anion ion pairs, with chiral ...

Synthesis and characterization of amphiphilic nitroxide 1,1,3,3–tetraethylisoindoline–2–oxyl–5–sodium sulfonate (TEIOSNa)

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract The synthesis and characterization of an amphiphilic nitroxide to be used as a controlling agent in a nitroxide‐mediated living radical polymerization in aqueous dispersion media is presented. In the first stage of nitroxide synthesis (phthalimide protection), two reaction methods were employed: traditional and microwave.

Revisiting the synthesis of dimethyl carbonate from methanol and carbon dioxide

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract The process for producing dimethyl carbonate (DMC) from carbon dioxide (CO2) and methanol is explored in this article. It provides an overview of the thermodynamics involved in DMC synthesis, discussing the challenges and potential solutions. The article highlights the reported use of catalysts and dehydrating agents to improve DMC yield and ...

Remote Migratory Reductive Arylation of Unactivated Alkenes Enabled by Electrochemical Nickel Catalysis

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
we have developed an electrochemical Ni−H catalyzed arylation coupling method of unactivated alkenes with aryl halides. The method displays broad functional group tolerance and proceeds under very mild conditions. Furthermore, aryl chlorides were also compatible substrates in this catalytic system. This conversion holds significant implications for the
