text: * Methyl esters are often susceptible to decarboxylation in the Krapcho decarboxylation.
  * Phenyl esters react to hydroxyarylketones in the Fries rearrangement.
  * Specific esters are functionalized with an α-hydroxyl group in the Chan rearrangement.
  * Esters with β-hydrogen atoms can be converted to alkenes in ester pyrolysis.
  *A direct conversion of esters to nitriles.
  * Pairs of esters are coupled to give α-hydroxyketones in the acyloin condensation
