General description

3,3-Dimethyl-2-butanol is a potential precursor for prohibited chemical weapons such as soman, a nerve agent. It is a synthetic analog of kairomone.

Application

3,3-Dimethyl-2-butanol (pinacolyl alcohol) can be used as a substrate:
  • To study the oxidation of secondary alcohols to ketones using cyclic microwave heating technique.
  • To prepare aryl ethers by reacting with aryl iodide using 4-pyrrolidinopyridine ligand via Cu-catalyzed Ullmann reaction.
3,3-Dimethyl-2-butanol was used in conversion of ribose- and glucose-binding proteins into receptors for pinacolyl methyl phosphonic acid.
