What is (DHQD)2PHAL?

Description

Hydroquinidine 1,4-phthalazinediyl diether, commonly abbreviated as (DHQD)2PHAL, is a widely used ligand for the Sharpless asymmetric dihydroxylation reaction. Nobel Prize–winning (2001) chemist K. Barry Sharpless and coauthors?reviewed its use?in 1994. It is sold by Sigma-Aldrich–Fluka.

The Uses of (DHQD)2PHAL

(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.
