Diisopropylamine is used as a precursor to prepare lithium diisopropylamide and sulfenamides, which are used in rubber vulcanization. It is also involved in the synthesis of N,N-Diisopropylethylamine (Hünig's base) obtained by alkylation with diethyl sulfate. Diisopropylammonium bromide is a bromide salt of DIPA used as an inert alternative to barium titanate. It is widely used as solvent as well as an intermediate in the the synthesis of pharmaceuticals, dyes, mineral flotation agents and emulsifiers.


Air sensitive. Keep container tightly closed in a dry and well-ventilated place. Incompatible with strong acids, strong bases, strong oxidizing agents and plastics.

Precursor of the sterically-hindered strong base lithium diisopropylamide (LDA), which has a greater "kinetic-basicity" than some thermodynamically stronger bases, e.g. alkyllithiums, and therefore finds wide application in lithiation reactions. LDA is a particularly useful base for the preparation of carboxylic acid dianions and ester enolates. For a review, see: Synthesis, 521 (1982).

LDA is generally prepared in situ by reaction of diisopropylamine with an alkyllithium; numerous examples in Org. Synth. Coll., 6, 7, 8, 9, and subsequent annual volumes. For discussion of methods for preparation, including Li metal in the presence of an aromatic hydrocarbon as electron-acceptor, see: Synthesis, 463 (1979); see also (Li in ether): Liebigs Ann. Chem., 1471 (1980).

LDA cleaves 1,3-dithiolanes (ethylene dithioacetals) to the carbonyl compounds: Synthesis, 1087 (1982):

1,3-Dithianes are not cleaved under these conditions.
