The co-operative stabilizations associated with the bending of the σ_C–C toward C–F bonds and total hyperconjugative generalized anomeric effect in the cis-configuration of 1,2-difluoroethene overcome the destabilizations associated with the exchange component and dipole–dipole interactions, leading to the preference of the cis-configuration in the compound.

The present paper reports a new hybrid cyclohexaphosphate which was characterized by different techniques (NMR, IR, UV-vis) and evaluated (electrical and biological). This reported compound exhibits an acidic character which is rarely observed with this type of condensed phosphate. In addition, this material is distinguished from others by its higher thermal stability and more pronounced antioxidant activity.

A series of carbon-based solid acid catalysts derived from biomass was prepared and used for the conversion of fructose to 5-HMF, which is a very important platform chemical due to its unique chemical structure. The results suggest that sulfonated carbon materials exhibit remarkable catalytic capability for fructose dehydration to 5-HMF.

The catalytic activity of nanofibre sepiolite as a green and non-toxic catalyst was investigated in the synthesis of chromene derivatives.

Polyurethanes (PUs) were synthesised using methylene diphenyl diisocyanate (MDI), polytetrahydrofuran ether diol (PTMG), and chain extenders containing different amounts of aliphatic side chains. Hybrid materials were then prepared by reacting the PUs with nano-TiO₂. The effects of different molecular structures of the chain extenders on the surface properties of PU coatings and the hybrid materials were investigated.

N,N-Dialkyl-N′-chlorosulfonyl chloroformamidines 1 reacted regioselectively with benzimidazoles bearing an activated methylene group at C2 to afford derivatives of the new benzo[4,5]imidazo[1,2-b][1,2,6]thiadiazine ring system. Substitution reactions of the new system occurred selectively at N5 (not at N2).

Crystal structures of tetraiodoallene, C₃I₄, and 2,2-diiodoacrylic acid, I₂C=CH(CO₂H), are reported.

A series of injectable oxi-CMC/PAH hydrogels was prepared via a Schiff base reaction under physiological conditions. The oxi-CMC6/PAH3 hydrogel exhibited good comprehensive properties and in vitro sustained release of BSA, showing that it could be potentially applied in the fields of drug delivery vehicles, tissue engineering, and cell encapsulation materials.
