Secrets of a university tutor: tetrahedral intermediates.

Sunday, January 8th, 2012

The tetrahedral intermediate is one of those iconic species on which the foundation of reaction mechanism in organic chemistry is built. It refers to a (normally undetected and hence merely inferred) species formed initially when a nucleophilic reagent attacks a carbonyl compound. Its importance to understanding the activity of enzymes cannot be overstated. An example of this genre is shown below, in which a thiol reacts with an acyl cyanide to form the species ringed in green.
