An Iron‐Catalyzed Sustainable Functional Group Transfer Strategy for In‐Water Transformation of Organic Sulfides to Sulfoxides by a Hydroxylamine‐Derived Oxidant

open access: yesChemSusChem, EarlyView.
An iron‐catalyzed ecofriendly reaction protocol is demonstrated to chemoselectively convert readily available organic sulfides to valuable sulfoxides, under mild reaction conditions in water. The functional group tolerance, scalability, reaction compatibility, and potential application make the protocol highly attractive in terms of green and ...

Multigram‐scale organic synthesis by Resonant Acoustic Mixing. Application to the Sustainable Preparation of Active Pharmaceutical Ingredients.

open access: yesChemSusChem, Accepted Article.
Three different reaction types were extensively studied at multi‐gram scale by Resonant Acoustic Mixing (RAM): i) the Knoevenagel condensation to vanillin barbiturate, ii) the Biginelli multicomponent reaction (MCR) to dihydropyrimidinones, which includes the anticancer drug (±)‐Monastrol, and iii) the Biltz synthesis to the antiepileptic drug ...

Recent Green and Sustainable Pd‐Catalyzed Aminations

open access: yesChemSusChem, Accepted Article.
Pd‐catalyzed aminations, while a powerful and commonly employed method of C‐N bond construction, often relies on unsustainable technologies that utilize: egregious organic solvents, high temperatures, long reaction times, and high catalyst loadings, especially of palladium.

A greener and more scalable synthesis of biogenic polydisulfides from lipoic acid

open access: yesChemSusChem, Accepted Article.
Ring‐opening polymerization (ROP) of 1,2‐dithiolanes form polydisulfides, an emergent class of dynamic covalent polymers. However, both monomer and polymer syntheses typically require anaerobic and moisture‐free conditions, often employing hazardous reagents and solvents that limit scalability. Herein, we disclose efficient, scalable syntheses for poly(
