(DHQD)2PHAL Chemical Properties,Usage,Production

Uses

(DHQD)2PHAL is a monomeric cinchona alkaloid dimer used as a catalyst for asymmetric halogenations.

Uses

(DHQD)2PHAL may be used as ligand for:

  • Osmium trioxide catalyzed asymmetric dihydroxylation of olefins.
  • Palladium catalyzed Suzuki-Miyaura coupling of aryl/heteroaryl halides with aryl boronic acids in aqueous medium and in the absence of phosphine/organic solvent.
  • Copper(I)-catalyzed azide-alkyne cycloaddition reaction to synthesize 1,2,3-triazoles in water.

General Description

(DHQD)2PHAL is a modified cinchona alkaloid derivative mainly used as a ligand for enantioselective catalysis.
