White to pale yellow crystalline powder | [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. | [Uses]
Catalyst for:
- Molybdenum hexacarbonyl-mediated Pauson-Khand reactions
- Rhodium-catalyzed hydroformylation reaction
| [storage]
Commercial material (97-98%) is satisfactory as received. The toxicological properties of the reagent are unknown. |
