Tohu Hua

Ko te waikawa 2-Fluoro-5-bromobenzoic he pūhui waro. E whai ake nei he kupu whakataki mo ona rawa, ona whakamahinga, tikanga whakangao, me nga korero haumaru:

āhua:
Ko te waikawa 2-Fluoro-5-bromobenzoic he matū totoka me te ahua kirikiri ma. Kare e rewa i roto i te wai i te pāmahana rūma, engari ka whakarewahia ki etahi whakarewa waro penei i te waihano me te dimethylformamide. He kaha te kawatanga, ka taea te tauhohe ki te kawakore ki te hanga tote rite.

Kaupapa:
Ko te waikawa 2-Fluoro-5-bromobenzoic he takawaenga e whakamahia nuitia ana i roto i te whakahiato waro.

Tikanga hanga:
Ko te tikanga whakarite o te waikawa 2-fluoro-5-bromobenzoic he tino ngawari. Ko te tikanga noa ko te whiwhi ma te fluorination o te waikawa bromobenzoic. Inaa, ka taea te tauhohe i te waikawa bromobenzoic me nga reagents fluorinating penei i te ammonium fluoride me te zinc fluoride ki te whakaputa waikawa 2-fluoro-5-bromobenzoic.

Nga korero haumaru: Me mau nga taputapu tiaki tika i te wa e mahi ana kia kore e pa ki te kiri, ki nga kanohi, ki te punaha manawa ranei. Me whakamahi i roto i te waahi hau pai me te karo i te hoha i te puehu me te hau. Mena ka pohehe te kai, ka pa mai ranei te mamae, me rapu wawe i te rongoa.

Tōmua: 2-BROMO-6-FLUOROPYRIDINE (CAS # 144100-07-2)

Panuku: Dodecyltributylphosphonium Bromide (CAS # 15294-63-0)
