In this blog, we showcase how benchtop NMR is an accessible and versatile tool for chemists and non-chemists to evaluate greener methods.

Tautomers are constitutional isomers that interconvert into each other by an exchange reaction, most commonly a proton transfer. Such two isomers can for example be a ketone and an enol. Keto-enol tautomerism (KET) becomes possible when there are hydrogen atoms adjacent to a carbonyl group (these hydrogen atoms are called α hydrogens). This tautomerism is depicted in Scheme 1 and is also discussed…

2,4-pentanedione (aka acetylacetone, acetylacetonato or acacH) is not only a ubiquitous ligand (AND ligand precursor!) for beautifully coloured organometallic complexes[1-3].. Read more.
