On‐Demand Deconstructable Thermosets Through Cleavable Comonomer and Thermolatent Base Synergy

open access: yesAngewandte Chemie, EarlyView.
Thermosets, valued for their chemical and mechanical properties, resist recycling due to their cross‐linked structure. Weak bonds via comonomers enable degradability, but diffusion limits effectiveness. We incorporate thermolatent bases before polymerization (thermal or 3D‐VAT printing).

Difluoromethylenation of Alkynes: Streamlined Access to Allyl Difluorides

open access: yesAngewandte Chemie, EarlyView.
Stabilizing primary oxocarbenium in HF/pyridine unlocks a direct alkyne difluoromethylenation – an efficient route to synthetically‐relevant allyl difluorides in a single step. ABSTRACT A direct difluoromethylenation of alkynes has been developed using HF/pyridine as a dual acidic and fluorinating medium. The reaction proceeds via in situ generation of

Derivatives of Aluminium with Glycols and Catechol

open access: yes, 1962
Reactions of aluminium isopropoxide with glycols (ethylene, 1,3-, 2, 3-, 1.4.butylene, bexylene glycols, and pinacol) have been studied. The reaction in the molar ratio of 1:1 affords monoisopropoxy glycollates whereas the reaction with excess of glycols

Photo‐Switchable Molecular Module Programming PET Biodegradation in Aquatic Environments

open access: yesAdvanced Functional Materials, EarlyView.
We address the plastic durability paradox by integrating an itaconic acid–derived pyrrolidone module into polymer backbones. Sunlight in water triggers Norrish Type I ring‐opening and hydrophilization, enabling rapid biodegradation into nontoxic minerals.

Synthesis and crystallinity of poly(butylene 2,5-furandicarboxylate)

open access: yes, 2012
Poly(butylene 2,5-furandicarboxylate) (PBF) was obtained by esterification of 2,5-furandicarboxylic acid (FDCA) and 1,4-butylene glycol (BG). By using H-1 NMR at 750 MHz to recognize the trace end groups at different polymerization stages, the study ...
