TRIISOPROPYLSILYLTRIFLUOROMETHANESULFONATE CAS:80522-42-5

Triisopropylsilyltrifluoromethanesulfonate, e tsejoang hape e le TIPSTf, e bonts'a lits'ebetso tse fapaneng k'hemistring ea tlhaho le saense ea thepa. E 'ngoe ea ts'ebeliso ea eona ea mantlha ke reagent e feto-fetohang bakeng sa ts'ireletso le ts'ebetso ea lihlopha tsa hydroxyl limolek'huleng tsa tlhaho. TIPSTf e nolofalletsa liphetoho tse khethiloeng ka ho fetola ts'ebetso ea hydroxyl, ho nolofatsa tlhahiso ea metsoako e rarahaneng, metsoako ea meriana, le lisebelisoa tse sebetsang tse nang le thepa e itseng e etselitsoeng lits'ebetso tse fapaneng. K'hemistring ea meriana, Triisopropylsilyltrifluoromethanesulfonate e bapala karolo ea bohlokoa ho sibolloeng ha lithethefatsi le nts'etsopele ka ho thusa ho qaptjoa ha limolek'hule tse sebetsang le bakhethoa ba meriana. Reaction ea eona e lumella bafuputsi ho fetola lihlopha tse sebetsang meahong ea tlhaho, e leng se lebisang ho thehoeng ha lintho tse ncha tsa meriana tse nang le mesebetsi e ntlafalitsoeng ea baeloji le liprofaele tse ntlafalitsoeng tsa meriana tse loketseng ts'ebeliso ea kalafo. Ho feta moo, TIPSTf e fumana thuso k'hemistring ea polymer bakeng sa ts'ebetso ea libaka tsa polymer le phetoho ea liketane tsa polymer. Ka ho kenyelletsa li-derivatives tsa TIPSTf ho matrices ea polymer, bo-rasaense ba ka etsa lisebelisoa tse nang le thepa e ntlafalitsoeng joalo ka matla a ho khomarela, ho tšoarella, le ho hanyetsa lik'hemik'hale, ho sebeletsa lits'ebetso ho lipente, likhomaretsi le metsoako e tsoetseng pele ea polymer. Lefapheng la tlhahiso ea lintho tse phelang, Triisopropylsilyltrifluoromethanesulfonate e sebetsa e le reagent ea bohlokoa bakeng sa ho khothaletsa liketso tsa ho theha maqhama a carbon-carbon le carbon-heteroatom. Mosebetsi oa eona oa ho susumetsa o thusa kaho ea meralo e rarahaneng ea limolek'hule le tlhahiso ea lik'hemik'hale tse ikhethang, o tlatsetsa tsoelo-peleng ea mekhoa ea maiketsetso le tlhahiso ea lik'hemik'hale tse ntle, lik'hemik'hale tsa temo le li-precursor tsa meriana. Ho feta moo, TIPSTf e sebelisoa ho catalysis bakeng sa ho potlakisa liphetoho tsa lik'hemik'hale le ho nolofalletsa ho sibolloa ha litsela tse ncha tsa karabelo. Jwalo ka catalyst ea Lewis acid, e ntlafatsa sekhahla sa karabelo le khetho, e lebisang litseleng tse sebetsang tsa maiketsetso bakeng sa ho lokisa metsoako ea boleng bo holimo le thepa e sebetsang lipatlisisong tsa thuto le lits'ebetsong tsa indasteri. Ka kakaretso, TRIISOPROPYLSILYLTRIFLUOROMETHANESULFONATE e bontša ho tenyetseha le bohlokoa e le reagent ea bohlokoa le catalyst ho etseng metsoako ea tlhaho, ho sibolloa ha lithethefatsi, saense ea polymer, catalysis le moralo oa thepa, e bonts'a tšusumetso ea eona e pharaletseng lipatlisisong tsa saense le boqapi ba theknoloji libakeng tse ngata.
