I-Methyl (Triphenylphosphoranylidene)i-acetate (CAS: 2605-67-6) isetshenziswa
1. I-Methyl (i-Triphenylphosphoranylidene) i-acetate isetshenziswa ekuphenduleni kwe-olefination.I-Wittig reagent ye-homologation enamakhabhoni amabili we-aldehyde kuya ku-α,β-unsaturated esters.ibhekana nokusabela kwe-Wittig ne-aldehydes ukunikeza esikhundleni se-methyl acrylates.
2. isetshenziswe ekuhlanganiseni okuphumelelayo kwe-pyrazoles ngokusabela nge-methyl diazoacetate phambi kwe-triethylamine.
3. Isetshenziswa ekulungiseni i-(triphenylphosphoranylidene)-ketene.
4. Ukusabela kwe-Wittig esikwenzile ekilasini kwakuhilela ukusabela kwe-2-nitrobenzaldehyde (1) nge-methyl (triphenylphosphoranylidene) acetate (2) ukukhiqiza i-methyl (2E) -3-(2-nitrophenyl) acrylate (3) nge-triphenylphosphine oxide. (4) umkhiqizo oseceleni, futhi senzeka ku-matrix yejeli yesilika ukuze kuqinisekiswe ngisho nokuhlakazeka komkhiqizo we-chromatography.
