Verwenden
tert-Butyl acetoacetate is used as intermediate for the syntheses of different organic chemicals. Raw material in pharmaceutical Industry, In agrochemical industry. Reagent for Acyloin synthesis and ?,β - unsaturated ketones synthesis.
Allgemeine Beschreibung
tert-Butyl acetoacetate (
t-BAA) is a cheap and easy to store commercial reagent. Reaction demonstrated that the more hindered tert-butyl acetoacetate (t-BAA, la) is ca.15-20-fold more reactive than the more commonly used methyl or ethyl analogs. It is widely employed as an acetoacetylating reagent.
läuterung methode
