2605-67-6 - Risk and Safety:
2605-67-6 - Application:
Risk Codes R36/37/38 - Irritating to eyes, respiratory system and skin. R25 - Toxic if swallowed Safety Description S22 - Do not breathe dust. S24/25 - Avoid contact with skin and eyes. WGK Germany 3 TSCA Yes HS Code 2931900090Methyl (Triphenylphosphoranylidene)acetate (CAS: 2605-67-6) is used 1. Methyl (Triphenylphosphoranylidene)acetate is used in olefination reactions. Wittig reagent for the two-carbon homologation of aldehydes to α,β-unsaturated esters. it undergoes the Wittig reaction with aldehydes to give substituted methyl acrylates. 2. used in an efficient synthesis of pyrazoles via reaction with methyl diazoacetate in the presence of triethylamine. 3. It is used in the preparation of (triphenylphosphoranylidene)-ketene. 4. The Wittig reaction we performed in class involved the reaction of 2-nitrobenzaldehyde (1) with methyl (triphenylphosphoranylidene) acetate (2) to produce methyl (2E)-3-(2-nitrophenyl) acrylate (3) with a triphenylphosphine oxide (4) side product, and took place in a silica gel matrix to ensure even product dispersion for chromatography.
