green chemistry

Diels-Alder (DA) reactions result in the formation of two carbon-carbon bonds of six-membered ring structures with high atom economy. The use of unsaturated organoboranes, which are widely available and exhibit low toxicity, enables the modulation of reactivity and selectivity in these reactions and also allow a variety of subsequent transformations the carbon-boron bond. These characteristics align these reactions with the principles of green chemistry.

Fluoropolymers, notably poly(vinylidene fluoride-co-hexafluoropropylene) (PH), are rendered to be an excellent choice for superior performance coatings attributed to their exceptional mechanical robustness, thermal resistance, and resistance to chemical attack. However, their low surface energy results in poor adhesion to metal substrates, limiting their application in critical corrosion-resistant systems. To address this challenge, PH was hydroxyl-modified (PHOH) to introduce active functional groups that enhance bonding capabilities.

In this work we assess water quality through physicochemical analyses while incorporating an Analytical GREEnness metric approach to evaluate the sustainability of the analytical methods employed.

The challenge of plastic waste management has intensified globally due to the non-biodegradable nature and fossil-based origin of most plastics. This research presented explores a novel approach to plastic upcycling through ideal catalytic cracking, with a focus on greener reaction conditions, such as supercritical CO₂ (scCO₂) processing.

Among the most active areas of chemistry research today is that of carbon dioxide utilization: an area of research that was viewed as futile and commercially impractical not so long ago due to the energetic stability of the CO2 molecule. The breakthroughs that largely began in earnest in the 1990s have accelerated and now make up a diverse and plentiful portfolio of technological and scientific advances and commercialized technologies.

In recent decades there has been uprising interest in the medicinal properties of organoselenides. These ubiquitous structural have their wide applications in material sciences, in catalysis and modern organic transformations. Research studies have led to important discoveries regarding selective C–Se bond formation and in this context a notable approach is direct selenylation. In this regard, nitrogen- or oxygen-containing arenes with organoselenides have appeared as a very important class of molecules, with diverse applications in the biological sciences.
