Literature References

Used catalytically to initiate deprotonation of a ketone with sodium hydride: Org. Synth. Coll ., 7, 351 (1990). Has been used to generate various bases by deprotonation; e.g. the highly-hindered bases potassium triethylmethoxide: Synthesis, 427 (1974), and potassium 2,6-di-t-butylphenoxide (see 2,6-Di-tert-butyl­phenol, A17244). For generation of the strong base potassium 3-aminopropylamide (KAPA), see 1,3-Diaminopropane, A11932. o-Alkynylanilines cyclize to indoles with KH in NMP; NaH is ineffective: Angew. Chem. Int. Ed., 39, 2488 (2000):

Applications

Potassium hydride is a precursor in the production of various bases by deprotonation, highly-hindered bases potassium triethylmethoxide and potassium 3-aminopropylamide It serves as a powerful base in organic synthesis of deprotonate carbonyl compounds and amines to form enolates and amides respectively.
