I-Methyl (Triphenylphosphoranylidene)i-acetate (CAS: 2605-67-6) isetyenziswa
1. I-Methyl (i-Triphenylphosphoranylidene) i-acetate isetyenziswa kwi-olefination reactions.I-Wittig reagent ye-carbon homologation ye-aldehydes kwi-α,β-unsaturated esters.ifumana i Wittig reaction kunye ne aldehydes ukunika endaweni ye methyl acrylates.
2. isetyenziswe kwi-synthesis esebenzayo ye-pyrazoles ngokuphendula kunye ne-methyl diazoacetate phambi kwe-triethylamine.
3. Isetyenziselwa ukulungiswa kwe (triphenylphosphoranylidene) -ketene.
4. I-reaction ye-Wittig esiyenzayo eklasini ibandakanya ukusabela kwe-2-nitrobenzaldehyde (1) kunye ne-methyl (triphenylphosphoranylidene) i-acetate (2) ukuvelisa i-methyl (2E) -3- (2-nitrophenyl) acrylate (3) kunye ne-triphenylphosphine oxide. (4) imveliso yecala, kwaye yenzeke kwi-silica gel matrix ukuqinisekisa nokuba ukusasazwa kwemveliso yechromatography.
