• 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.
