Potassium hydride is a strong base and hydride donor to Lewis acids. It is generally employed in organic reactions like deprotonation, rearrangement, and elimination reactions. It is also used as a reducing agent to reduce hindered boranes and borates to substituted borohydrides.
Potassium hydride in paraffin can be used as a base in:
Wittig reaction of various aldehydes with high Z selectivity.
Williamson ether synthesis to prepare substituted ethers from alcohols.
Polymerization of ethylene oxide to yield polyethylene glycols.
