Adaptive Rhodium Catalysis with a Lewis‑Acidic Secondary Sphere for Divergent Hydrogenation of Propargylic Alcohols

open access: yesAngewandte Chemie, EarlyView.
Adaptive rhodium catalysis with a Lewis‐acidic secondary sphere enables divergent hydrogenation of propargylic alcohols into alkynes, allylic ethers, or alkenes. Catalyst design and condition‐dependent pathways provide practical guidance for chemoselectivity control.

Unprecedented Selectivity for Arsenic(III) in a Dimercaptosuccinic Acid‐Based Zr‐MOF: The Role of Dangling Ligands

open access: yesAngewandte Chemie, EarlyView.
Highly defective DMSA‐based zirconium metal–organic framework (Zr‐DMSA‐MOF) removes arsenic from water with higher selectivity over phosphate than conventional Zr‐MOFs. X‐ray absorption spectroscopy, pair distribution function analysis, and solid‐state NMR reveal that, unlike other Zr‐based MOFs where arsenic binds to the clusters, the flexible ...

Upcycling of Waste Plastics into Carboxylic Acids for Biodegradable Surfactants

open access: yesAngewandte Chemie, EarlyView.
Biodegradable surfactants have now been created from post‐consumer waste HDPE. High conversion (>80%) is maintained throughout all major process steps including pyrolysis, hydroformylation, and oxidation. The utility of the plastic‐derived carboxylate surfactant is confirmed via critical micelle concentration, surface tension, and foaming measurements.
