Application

Bis(diisopropylamino)chlorophosphine has been used in the synthesis of tert-butyl tetraisopropylphosphorodiamidite ligand for palladium-catalyzed Buchwald–Hartwig amination reaction.

It is also can be used to synthesize:
  • acyclic N-phosphonio imine catalyst for selective epoxidations
  • boryl-substituted methylenephosphonium derivatives

Other Notes

Contains varying amounts of diisopropylamine hydrochloride
