설명

일반 설명

Diisopropylamine (DIPA) is an aliphatic secondary amine commonly used as an organic base in chemical synthesis.

애플리케이션

Diisopropylamine can be used as:

• A reagent to synthesize furan, dihydrofuran, or butanolide derivatives by reacting with γ-ketothioesters.
• A catalyst to prepare aryl disulfides via oxidative coupling of aryl thiols in the presence of air as an oxidant.
• A base in Pd-catalyzed cross-coupling reactions such as Heck and Sonogashira reaction.

It can also be used as a starting material to prepare lithium diisopropylamide (LDA), a strong non-nucleophilic base widely used in organic synthesis for deprotonation reactions.
