SN1 and SN2 reactions are fundamental types of nucleophilic substitution in organic chemistry, each with distinct mechanisms and characteristics. An SN1 reaction (Substitution Nucleophilic ...

A mild and scalable electrolysis of carboxylic acids can provide streamlined access to valuable alkene feedstocks at kilogram scale. Using rapidly alternating polarity (rAP), the team in the US were ...

The carbonyl-alkyne metathesis (CAM) reaction is a versatile, stereoselective, and atom-economical method to access a diverse range of α,β-unsaturated carbonyl compounds, which are useful synthetic ...

In the realm of reactivity, the vinyl carbocation is a beast so fleeting, so keen to combine or rearrange, that many have doubted that it can be tamed to create molecules in a stereoselective way. But ...

It is easier to form more substituted carbocations because of destabilisation in the parent substrate, rather than stabilisation in the reactive intermediate, new research shows. 1 Nearly 20 years ago ...

Chemists have coaxed vinyl cations to insert into C–H bonds of alkanes and arenes. In doing so, they’ve shown that this classic carbocation is capable of much more than previously thought. Although ...
