Potassium 3-aminopropylamide, readily prepared in situ from KH and 3-aminopropylamine, effects rapid, multipositional isomerization of the triple bond in prop-2-ynylic and other acetylenic alcohols to the chain terminus remote from the hydroxy function, within minutes at 0–20 °C.
3-氨基丙酰胺钾很容易从KH和3-氨基丙胺中就地制备,可在0至数分钟内在几分钟之内迅速将丙-2-炔醇和其他炔醇中的三键快速多位异构化至远离羟基官能团的链末端20°C。
