Taw qhia
2,3-Difluorophenylacetic acid yog cov organic compound. Nws yog xim tsis muaj xim rau dawb nrog cov ntxhiab tsw ntxhiab ntawm chav tsev kub.
Nws kuj tuaj yeem siv rau qee qhov kev cuam tshuam hauv cov organic synthesis xws li carbonylation thiab hloov pauv.
Txoj kev npaj 2,3-difluorophenylacetic acid tuaj yeem ua tiav los ntawm kev qhia txog fluorine atom rau hauv phenylacetic acid. Cov txheej txheem kev npaj muaj xws li: cov tshuaj fluorination, cov tshuaj tiv thaiv alkyne thiab cov tshuaj txo cov tshuaj.
Kev nyab xeeb ntawm 2,3-difluorophenylacetic acid, uas yog ib qho tshuaj tiv thaiv uas yuav ua rau khaus ntawm daim tawv nqaij, qhov muag thiab ua pa thaum tiv tauj. Kev ceev faj yuav tsum tau ua thaum lub sijhawm ua haujlwm thiab siv, suav nrog hnav cov looj tsom iav thiab hnab looj tes uas tsim nyog, thiab ua kom muaj chaw ua haujlwm zoo. Cov tshuaj tiv thaiv xws li oxidants yuav tsum zam kom tsis txhob muaj kev phom sij.
