Isingeniso

I-2,3-Difluorophenylacetic acid iyinhlanganisela yezinto eziphilayo. Iqinile engenambala ukuya kokumhlophe enephunga elimnandi ekamelweni lokushisa.

Ingasetshenziswa futhi kokunye ukusabela ku-organic synthesis efana ne-carbonylation kanye nokufaka esikhundleni.

 

Indlela yokulungiselela i-2,3-difluorophenylacetic acid ingafinyelelwa ngokwethula i-athomu ye-fluorine ku-phenylacetic acid. Izindlela zokulungiselela ezivamile zihlanganisa: ukusabela kwe-fluorination, ukusabela kwe-alkyne kanye nendlela yokunciphisa amakhemikhali.

 

Ukuphepha kwe-2,3-difluorophenylacetic acid, okuwuketshezi olucasulayo olungabangela ukucasuka kwesikhumba, amehlo kanye nendlela yokuphefumula lapho uthintwa. Ukuqapha kufanele kuthathwe ngesikhathi sokusebenza nokusebenzisa, okuhlanganisa ukugqoka izingubo zamehlo zokuzivikela ezifanele namagilavu, nokuqinisekisa indawo yokusebenza enomoya omuhle. Ukusabela ngezinto ezifana nama-oxidants kufanele kugwenywe ukuvimbela izingozi.
