(METHOXYMETHYL)DIPHENYLPHOSPHINE OXIDE Chemical Properties,Uses,Production
Chemical Properties
White to pale yellow crystalline powder
Uses
Catalyst for:
- Molybdenum hexacarbonyl-mediated Pauson-Khand reactions
- Rhodium-catalyzed hydroformylation reaction
Application
Horner-Wittig reagent for the preparation of methoxyvinyl ethers and hence homologous aldehydes; the anion has greater stability and nucleophilicity than the analogous phosphonium ylide.
storage
Commercial material (97-98%) is satisfactory as received. The toxicological properties of the reagent are unknown.
