Grignard Reaction In Aroma Industry

Primary, Secondary or Tertiary alcohols can be prepared by the reaction of a suitable carbonyl-containing compound with an alkyl / Aryl magnesium halide (Grignard reagent). The reagent is usually obtained quite readily by adding an alkyl halide to a suspension of magnesium turnings in anhydrous ethers. Initiation of the reaction may require the addition of a few crystals of iodine, the purpose of which may be to form a catalytic amount of Magnesium Iodide or possibly simply to etch the metal surface. Aroma chemical manufacturing companies have utilized this reaction to Make many Aroma Chemicals.
