Trifluoromethylation wani nau'in sinadari ne na kwayoyin halitta wanda za'a iya shigar da kungiyoyin trifluoromethyl cikin kwayoyin halitta ta amfani da reagents tegafluor kamar TMSCF3.
Abubuwan da ke cikin tegafluor:
- Tegafluor shine muhimmin halayen juzu'i na rukuni, wanda zai iya gabatar da ƙungiyoyin trifluoromethyl tare da wani nau'in electron don canza yanayin jiki da sinadarai na kwayoyin.
- Ƙungiyoyin Trifluoromethyl suna da ƙarfin jan hankali na electron, wanda zai iya ƙara yawan electrophilicity na kwayoyin halitta da solubility na sauran ƙarfi.
- Samfuran halayen tegafluor gabaɗaya sun tsaya tsayin daka a cikin sinadarai kuma suna aiki da ilimin halitta.
Amfanin tegafluor:
- A fagen kimiyyar kayan aiki, tegafluor na iya canza yanayin saman kayan, ƙara kwanciyar hankali da juriya na yanayi.
Hanyar shiri na tegafluor:
- Reagents na tegafluor da aka fi amfani da su sun haɗa da: TMSCF3, Ruppert-Prakash reagent, da sauransu.
- Yawancin halayen Tegafluor ana aiwatar da su ne a cikin yanayi mara kyau, ta amfani da sauran ƙarfi mara ƙarfi (misali, methylene chloride, chloroform) azaman matsakaiciyar amsawa.
