Life is sweet….maybe too sweet!

Sugar substitutes are gaining more and more relevance due to the health problems associated with the consumption of high amounts of sugar...I thought it would be interesting to take a few of those substitutes and acquire their proton NMR spectrum in our benchtop NMR.

Electronegativity and Chemical Shift

Electronegativity is a concept that we have to study and understand early in our science or engineering degrees. In chemistry this concept stays with us and we commonly invoke it in order to explain multiple phenomena what we observe or study…and of course, NMR is not the exception!

What's the 'ism' of today? Keto-Enol Tautomerism

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 more here.
