Preparative Methods of 4-Dimethylamino-3-butyn-2-one: bromination of 4-(dimethylamino)but-3-en-2-one leads essentially in quantitative
yield to the hydrobromide which is treated with Triethylamine. Further treatment with Potassium t-Butoxide
leads to the title reagent.[1-2] | [storage]
4-Dimethylamino-3-butyn-2-one is thermally unstable and is best stored at below -50 °C if kept for a
prolonged period.
