Polyimidazoles via aromatic nucleophilic displacement [PDF]
Polyimidazoles (PI) are prepared by the aromatic nucleophilic displacement reaction of di(hydroxyphenyl) imidazole monomers with activated aromatic dihalides or activated aromatic dinitro compounds. The reactions are carried out in polar aprotic solvents

Enantioenriched α‐/β‐/γ‐thiocarboxylic acids featuring C–S chirality are valuable targets in organic synthesis. This review outlines recent progress in their asymmetric synthesis, including chiral pool approaches, metal‐ /organo‐catalysis, and emerging biocatalytic strategies. Enantiomerically pure α‐/β‐/γ‐thiocarboxylic acids bearing a stereocentre at

What went wrong? The flawed concept of cerebrospinal venous insufficiency [PDF]
In 2006, Zamboni reintroduced the concept that chronic impaired venous outflow of the central nervous system is associated with multiple sclerosis (MS), coining the term of chronic cerebrospinal venous insufficiency ('CCSVI'). The diagnosis of 'CCSVI' is

Microwave‐Assisted One‐Pot Synthesis of Alkyl Levulinates From Post‐Harvest Vegetable Waste
Vegetable waste is valorized through Soxhlet extraction using H₂O₂ and heteropolyacid (HPA), followed by material characterization (XRD, FTIR, TGA, DSC). A microwave‐assisted reaction at 170 °C for 30 min with HPA and alcohol yields bio‐based esters.

Bisphenol‐A polycarbonate is upcycled via a simple one‐pot reaction into an aromatic Mannich polyol, which serves as a precursor for fabricating poly(urethane‐isocyanurate) (PUR‐PIR) aerogels. PUR‐PIR aerogels, prepared with different isocyanate indices, exhibit high porosities, high specific surface areas, ultralow thermal conductivity, and excellent ...
