Potassium hydride, KH, is the inorganic compound of potassium and hydrogen. It is an alkali metal hydride. It is a white solid, although commercial samples appear gray. It is a powerful superbase that is useful in organic synthesis. It is sold commercially as a slurry (~35%) in mineral oil or sometimes paraffin wax to facilitate dispensing. [3]

2012年2月1日 · Noted chem-blogger Milkshake seems to have had a close call with a fire started by a tiny potassium hydride residue. It looks like he made it through without serious injury, but that sort of thing will definitely shake a person up.

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 and sodium hydride are flammable solids that ignite on contact with moist air. Potassium hydride presents a more serious fire hazard than sodium hydride. The mineral oil dispersions do not ignite spontaneously on exposure to the atmosphere.

Treatment of 3,3,8-tribromocamphor 304 with potassium anilide (generated in situ from potassium hydride and aniline) in THF at room temperature for 7 h lead to an interesting tricyclic compound 306 in 85%.
