Ethyl 4,4-difluoro-3-oxobutyrate CAS:352-24-9

Ethyl 4,4-difluoro-3-oxobutyrate e na le sebopeho moo sehlopha sa difluoromethyl (-CF2) se hoketsweng mokokotlong wa β-ketoester, mme e nngwe ya dihydrogen e nkeloa sebaka ke sehlopha sa ethyl (-C2H5). Sebopeho sena sa sebopeho se susumetsa dibopeho tsa sona tsa mmele le tsa dikhemikhale. Hangata se teng e le mokelikeli o se nang mmala o nang le ntlha e belang e ka bang 130°C le bongata ba hoo e ka bang 1.27 g/cm³. Motswako o qhibiliha hanyane ka metsing empa o qhalana habonolo dihlahisweng tsa tlhaho tse kang ethanol le acetone. Ditshebediso Indasteri ya Monko: Ethyl 4,4-difluoro-3-oxobutyrate e sebediswa haholo lefapheng la monko o monate ka lebaka la monko wa yona wa ditholwana. E sebetsa e le motsoako wa bohlokwa dinokong, di-cologne, le dihlahisweng tse ding tse nkgang monate. Ho Kopanngwa ha Dikhemikhale: Motswako o sebetsa e le motheo wa kaho o feto-fetohang ho kopantsweng ha manyolo. O nka karolo dikarabelong tse fapaneng ho hlahisa di-derivatives tse bohlokwa indastering ya meriana le ya dikhemikhale. Bohareng: K'hemistring ea lintho tse phelang, ethyl 4,4-difluoro-3-oxobutyrate e sebetsa e le bohareng ba ho kopanya metsoako e rarahaneng haholoanyane, e tlatsetsang nts'etsopele ea thepa e ncha le lits'ebetso tsa lik'hemik'hale. Ho kopanya Ethyl 4,4-difluoro-3-oxobutyrate e ka etsoa ka mekhoa e 'maloa. Mokhoa o mong o tloaelehileng o kenyelletsa karabelo pakeng tsa ethyl acetoacetate le 2,2-difluoroethyl bromide tlas'a maemo a mantlha. Karabelo ena e lebisa ho thehoeng ha ethyl 4,4-difluoro-3-oxobutyrate e le sehlahisoa se seholo, se ka hloekisoang ho fumana chai e ngata le bohloeki. Ka bokhutšoanyane, ethyl 4,4-difluoro-3-oxobutyrate ke motsoako o feto-fetohang o bohlokoa tlhahisong ea monko o monate, tlhahiso ea lik'hemik'hale le lits'ebetsong tsa indasteri. Thepa ea eona e ikhethang, ho kenyeletsoa ho qhibiliha le sebopeho se itseng sa lik'hemik'hale, e etsa hore e be ea bohlokoa makaleng a fapaneng, e tlatsetsa haholo ho thehoeng ha lihlahisoa tse fapaneng tsa bareki le tsa indasteri.
