Acetoacetates Derived From Vegetable Oils: A Platform for Tailor‐Made Vinylogous Urethane Foams
Advanced Functional Materials, EarlyView.A renewable vegetable oil is converted into acetoacetate‐functionalized precursors for the preparation of catalyst‐free vinylogous urethane foams. Room‐temperature foaming with n‐pentane generates lightweight cellular materials, while the choice of amine enables control over foam structure and mechanical properties.

Conformer-specific polar cycloaddition of dibromobutadiene with trapped propene ions
Nature Communications, 2021 Identifying a concerted or stepwise mechanism in Diels–Alder reactions is experimentally challenging. Here the authors demonstrate the coexistence of both mechanisms in the reaction of 2,3-dibromobuta-1,3-diene with propene ions, using a conformationally

Switching off propene hydrogenation in the direct epoxidation of propene over gold-titania catalysts
, 2012 Low gold-loaded gold–titanium catalysts with very small gold nanoparticles for the direct epoxidation of propene have a remarkably high epoxidation activity. A disadvantage, however, is that these catalysts in certain cases also have a very high activity

Photo‐Degradable Polyester Networks and Multi‐Photon Printed Objects Based on Cyclic Ketene Acetals
Advanced Functional Materials, EarlyView.The current work introduces a photoreversible polyester network derived from radical ring‐opening polymerization of cyclic ketene acetals. It combines photoreversible cross‐linking with initiator‐free multi‐photon printing. Reversible network formation, tunable mechanical properties, and selective degradation highlight its potential as a versatile ...
