(METHOXYMETHYL)DIPHENYLPHOSPHINE OXIDE Usage And Synthesis

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.
