General description

N,N-diisopropylethylamine is an aliphatic sterically hindered amine.

Application

N,N-diisopropylethylamine may be used in the following processes:
  • As an organic base in the synthesis of indenopyrones.
  • As an activator for chiral iridium N, P ligand complexes which can be utilized in the hydrogenation of α,β-unsaturated nitriles.
  • As a non-nucleophilic base for substitution reaction.
  • As a starting material in the preparation of bis[1,2]dithiolo[1,4]thiazines and bis[1,2]dithiolopyrroles.
