Methyl (Triphenylphosphoranylidene)acetate (CAS: 2605-67-6) amagwiritsidwa ntchito
1. Methyl (Triphenylphosphoranylidene)acetate amagwiritsidwa ntchito muzochita za olefination.Wittig reagent ya kuphatikizika kwa ma carbon-awiri a aldehydes kupita ku α, β-unsaturated esters.imakumana ndi machitidwe a Wittig ndi aldehydes kuti apereke m'malo mwa methyl acrylates.
2. amagwiritsidwa ntchito mu kaphatikizidwe koyenera kwa pyrazoles kudzera mukuchita ndi methyl diazoacetate pamaso pa triethylamine.
3. Amagwiritsidwa ntchito pokonza (triphenylphosphoranylidene) -ketene.
4. Zomwe Wittig anachita m'kalasi zinkakhudza zomwe 2-nitrobenzaldehyde (1) ndi methyl (triphenylphosphoranylidene) acetate (2) kupanga methyl (2E) -3- (2-nitrophenyl) acrylate (3) ndi triphenylphosphine oxide. (4) mbali ya mankhwala, ndipo zinachitika mu silika gel osakaniza masanjidwewo kuonetsetsa ngakhale mankhwala kubalalitsidwa kwa chromatography.
