Imikhiqizo

I-3-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl) phenol, evame ukubizwa ngokuthi i-TMDBP, iyinhlanganisela yamakhemikhali enezinhlobonhlobo zokusetshenziswa kuzo zonke izimboni ezahlukene.Isakhiwo sayo samakhemikhali siqukethe i-boron-containing cyclic ether exhunywe eqenjini le-phenolic, okwenza kube inhlanganisela eguquguqukayo yezinhlelo zokusebenza ezihlukahlukene.Okunye ukusetshenziswa okuyinhloko kwe-3-(4,4,5,5-Tetramethyl-1,3,2 -dioxaborolan-2-yl)phenol isendaweni ye-organic synthesis.I-TMDBP ivame ukusetshenziswa njenge-boronic acid surrogate, ngenxa ye-athomu ye-boron ekhona esakhiweni sayo.Ingenza izibopho ezihlangene nezinhlobo ze-nucleophilic, njengama-organometallic reagents noma i-aryl lithium compounds, ngokusebenzisa i-boron, okwenza kube lula ukwakheka kwebhondi ye-carbon-carbon.Lesi sakhiwo senza i-TMDBP ibe ithuluzi elibalulekile ekwakhiweni kwama-molecule ezinto eziphilayo eziyinkimbinkimbi embonini yezesayensi yezemithi, ye-agrochemical, kanye nezinto.Isakhiwo sayo esiqukethe i-boron sivumela ukwethulwa kwama-athomu e-boron ezingxenyeni zezidakamizwa, okuvumela ukuguqulwa okwengeziwe noma izithuthukisi emsebenzini wabo webhayoloji.I-TMDBP ingasetshenziselwa ukuhlanganisa amaqembu e-boronic ester kuma-molecule ezidakamizwa, angadlala indima ebalulekile ekulethweni kwezidakamizwa noma ekwelapheni okuqondisiwe.Ukwengeza, isistimu yephunga elingenawo ama-electron ku-TMDBP ingaba nomthelela ekukhetheni kanye namandla ezidakamizwa, okulenze libe yisakhiwo esibalulekile sokwakhiwa kwemithi emisha.I-TMDBP nayo inezinhlelo zokusebenza emkhakheni wesayensi yezinto.I-athomu ye-boron esakhiweni sayo ingakha izakhiwo zokuxhumanisa nezisekelo zikaLewis.Lesi sakhiwo sivumela ukuhlanganiswa kwezinto ezisebenzayo ezinezakhiwo eziyingqayizivele.I-TMDBP isetshenziswe ekuthuthukisweni kwezinto ezikhanyayo, amakristalu awuketshezi, nama-polymers.Lezi zinto ezisetshenziswayo zingabonisa izici ezifana nokuzwa okubonakalayo, ukuphendula ngogesi, noma ukuhlelwa kwesakhiwo esithile, okuzenza zibaluleke kakhulu ezinhlelweni ezihlukahlukene zobuchwepheshe. Ngaphezu kwalokho, i-TMDBP isetshenziswa ekuhlanganiseni amakhemikhali e-agrochemicals, okungamakhemikhali asetshenziswa kwezolimo ukuze kuthuthukiswe ukukhula kwezitshalo nokuvikela ngokumelene nazo. izinambuzane noma izifo.Ikhono le-TMDBP lokwenza amabhondi e-carbon-carbon kanye nokwethula ama-athomu e-boron lingaba nomthelela ekuthuthukisweni kwamanoveli amakhemikhali e-agrochemicals anamandla athuthukisiwe kanye nokusimama kwemvelo.Kafushane, 3-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan -2-yl)phenol (TMDBP) iyinhlanganisela eguquguqukayo esetshenziswa ku-organic synthesis, imithi, isayensi yezinto zokwakha, kanye namakhemikhali ezolimo.Ukwakheka kwayo okuqukethe i-boron kwenza ukwakheka kwamabhondi e-carbon-carbon kanye nokwethulwa kwama-athomu e-boron abe ama-molecule, okuyenza ibe ithuluzi elibalulekile ekuhlanganiseni izinhlanganisela eziphilayo eziyinkimbinkimbi.I-TMDBP idlala indima ebalulekile ekwakhiweni kwezidakamizwa, izinto zokwakha ezinezakhiwo ezihlukile, namakhemikhali ezolimo esimeme endaweni ezungezile.Ngohlelo lwayo oluhlukahlukene lwezinhlelo zokusebenza, i-TMDBP inikela ekuthuthukisweni kwezimboni nemikhakha yesayensi ehlukahlukene.
