Novel Sulfur‐Containing Polyurethanes using 5‐(Chloromethyl)Furfural as a Renewable Building Block

open access: yesChemSusChem, EarlyView.
A novel methodology is presented for synthesizing biomass‐derived diols using 5‐(chloromethyl)furfural, thiols, and mild reaction conditions. These innovative diols are subsequently utilized in the production of new polyurethanes via polyaddition with both commercially available and biomass‐derived diisocyanates.

Plasmonic Catalysis for Controlling Selectivity in the Hydrogenation of Cinnamaldehyde to Propylbenzene Under Visible‐Light Irradiation

open access: yesChemSusChem, EarlyView.
A plasmonic Au@Au3Pd catalyst that integrates visible‐light‐driven hot electron generation with bimetallic electronic tuning to steer the selective hydrogenation of cinnamaldehyde toward propylbenzene is reported. Localized surface plasmon resonance excitation modulates reaction pathways on tailored Au–Pd interfaces, enabling product selectivity under ...

A C3‐Symmetric Diphenylethylendiamine‐Based Catalyst in the Asymmetric Michael Addition of α,β‐Unsaturated Ketones with 4‐Hydroxycoumarin and 4‐Hydroxyquinolin‐2‐One

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
Two C3‐symmetric organocatalysts with multiple amino groups are prepared and employed in the asymmetric addition of 4‐hydroxycoumarin and quinoline‐2‐one to unsaturated ketones. The all‐amino version of the catalyst induces the better stereoselectivity and provides the products in up to 95% yield.
