General description

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

Application

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.

Ortholithiation of 1-chloro-3-(trifluoromethyl)benzene with lithium diisopropylamide (LDA) in tetrahydrofuran at -78 °C displays characteristics of reactions in which aggregation events are rate limiting. Metalation with lithium-chloride-free LDA involves a rate-limiting deaggregation via dimer-based transition structures. The post-rate-limiting proton transfers are
