text: Classic organic reactions exist for the synthesis of acyloins. 
  * The acyloin condensation is a reductive coupling of esters
  * The benzoin condensation is condensation reaction between aldehydes catalyzed by a nucleophile
  * Oxidation of carbonyls is possible with molecular oxygen but not selective
  * Better alternative is oxidation of corresponding silyl enol ethers with mCPBA in the Rubottom oxidation
  * MoOPH oxidation of carbonyls is a system with molybdenum peroxide, pyridine and hexamethylphosphoramide.
