A number of (dialkylamino)allenes 2 have been obtained in excellent yields and in a reasonable state of purity by isomerization of dialkyl-2-propynylamines 1 with potassium tert-butoxide in tetrahydrofuran or with the complex t-BuOK*t-BuOH in hexamethylphosphoric triamide.Treatment of the 2-propynylamines with t-BuOK in dimethyl sulfoxide leads to equilibrium mixtures of the allenic amines 2 and dialkyl-1-alkynylamines 3.
