Khoom Description
Kev taw qhia thiab kev siv ntawm CAS 372-31-6|Ethyl 4,4, 4-trifluoroacetoacetate
Ethyl trifluoroacetoacetate yog ib qho tseem ceeb raw khoom rau cov synthesis ntawm cov tshuaj tua kab xws li fluopyrimifen, pyrifenacet, pyrifluphos, dithiopyr, thiflufenac, thiab diphenoxyfen. Tam sim no, txoj kev tsim khoom tseem ceeb yog txoj hauv kev rau kev npaj ethyl trifluoroacetoacetate los ntawm Claisen condensation cov tshuaj tiv thaiv siv ethyl trifluoroacetate thiab ethyl acetate ua raw khoom raws li kev ua ntawm sodium ethoxide.
Siv ua tshuaj tua kab intermediates. Kev Siv: Raws li qhov nruab nrab zoo, nws yog dav siv hauv kev sib xyaw ntawm cov tshuaj tua kab muaj fluorine, tshuaj, thiab cov organic intermediates. Raws li ib tug zoo intermediate, nws yog dav siv nyob rau hauv lub synthesis ntawm fluorine-muaj tshuaj tua kab, tshuaj, thiab organic intermediates. Cov tshuaj fluorine heterocyclic thiab tshuaj tua kab yog cov khoom nruab nrab tseem ceeb thiab lub tsev thaiv ntawm cov organic synthesis.
