| | (DHQD)2PHAL Usage And Synthesis |
| 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. |
