2605-67-6 - Daim Ntawv Thov:

Methyl (Triphenylphosphoranylidene) acetate (CAS: 2605-67-6) yog siv
1. Methyl (Triphenylphosphoranyliden) acetate yog siv rau hauv cov tshuaj olefination.Wittig reagent rau ob-carbon homologation ntawm aldehydes rau α, β-unsaturated esters.Nws dhau los ntawm Wittig cov tshuaj tiv thaiv nrog aldehydes los muab cov methyl acrylates hloov.
2. siv nyob rau hauv ib tug npaum synthesis ntawm pyrazoles ntawm cov tshuaj tiv thaiv nrog methyl diazoacetate nyob rau hauv lub xub ntiag ntawm triethylamine.
3. Nws yog siv rau hauv kev npaj ntawm (triphenylphosphoranylidene)-ketene.
4. Cov tshuaj tiv thaiv Wittig peb tau ua hauv chav kawm koom nrog cov tshuaj tiv thaiv ntawm 2-nitrobenzaldehyde (1) nrog methyl (triphenylphosphoranylidene) acetate (2) los tsim methyl (2E)-3-(2-nitrophenyl) acrylate (3) nrog triphenylphosphine oxide. (4) sab khoom, thiab coj qhov chaw nyob rau hauv ib tug silica gel matrix los xyuas kom meej txawm cov khoom dispersion rau chromatography.
