Description and Uses
2-Chloro-2-methylpropane is an alkylating agent that is used to functionalize molecules with tert-butyl group.
It serves as an effective chlorinating agent, in combination with the ionic liquid, 1-butyl-3-methylimidazolium bromide for converting alcohols into chlorides.
It can also be used to prepare tert-butyl ethers by treating with corresponding alcohols.
