Considering the oxidation potential of the enolate intermediate (Eox = -0.97 V) and the reduction potential of the aryl iodide (Ered = -2.24 V), single electron transfer from the enolate ...

The type I enzymes catalyze a cis-dehydration of 3-dehydroquinate via a covalent imine intermediate, while the type II enzymes catalyze a trans-dehydration via an enolate intermediate.

A Breslow intermediate is a chemical species having an enol skeleton, being formed by a reaction of aldehyde and N-heterocyclic carbene. It is regarded as an acyl anion equivalent. *4) Enolate ...
