4-Hydroxyphenylboronic acid pinacol ester, e tsejoang hape e le HBP ester, ke motsoako oa lik'hemik'hale o fumanang likopo likarolong tse sa tšoaneng ka lebaka la thepa ea eona e ikhethang e le boronic ester.Sebopeho sa eona sa lik'hemik'hale se na le athomo ea boron e kopantsoeng le sehlopha sa phenolic ka ho hokahanya ha ester, e leng se etsang hore e be mohaho oa bohlokoa oa mohaho bakeng sa organic synthesis. -ho kopanya maikutlo.Boitšoaro bona bo kenyelletsa ho thehoa ha carbon-carbon bond pakeng tsa aryl kapa vinyl boronic acid le aryl kapa vinyl halide kapa triflate.Joaloka ester ea boronic, HBP ester e sebetsa e le selelekela sa boronic acid e lumellanang, e ka kenang karabelo ea li-cross-coupling le li-electrophile tse sa tšoaneng, tse lebisang ho thehoeng ha limolek'hule tse rarahaneng.Karabelo ena e na le ts'ebeliso ea bohlokoa ho k'hemistri ea bongaka, motsoako oa agrochemical, mahlale a lintho tse bonahalang, le likarolo tse ling tse ngata tsa organic synthesis. Ho feto-fetoha ha maemo a HBP ester ho itšetlehile ka bokhoni ba eona ba ho etsa liphetoho tsa sehlopha se sebetsang, joalo ka oxidation kapa phokotso, ho kenyelletsa ts'ebetso e eketsehileng ho molek'hule.Ka mohlala, sehlopha sa hydroxyl sa phenolic moiety se ka sireletsoa 'me hamorao sa sireletsoa, ho lumella hore ho be le phetoho e khethehileng le ho fapanyetsana ha motsoako.Thepa ena e etsa hore HBP ester e be sesebelisoa sa bohlokoa ha ho etsoa lihlahisoa tsa meriana, li-agrochemicals, le lik'hemik'hale tse ling tse ntle.Ka lebaka la athomo ea boron ka sebopeho sa eona, e ka etsa li-complexes tse fetolehang tse nang le diol kapa polyols, joalo ka tsoekere kapa lik'habohaedreite.Thepa ena e nolofalletsa nts'etsopele ea li-sensor tse thehiloeng ho boronate bakeng sa ho lemoha tsoekere, hammoho le limolek'hule tse ling tse amanang le baeloji.HBP ester e ka kenyelletsoa liforomong tse fapaneng tsa kutlo, ho kenyelletsa le fluorescent kapa colorimetric probes, ho fana ka mokhoa oa ho lemoha bahlahlobisisi ba khethehileng ka mehlala ea likokoana-hloko kapa tsa tikoloho.Ntle le ts'ebeliso ea eona ho li-organic synthesis le lits'ebetso tsa kutlo, 4-Hydroxyphenylboronic acid pinacol ester le eona e 'nile ea batlisisoa. bakeng sa karolo e ka bang teng litsamaisong tsa phano ea lithethefatsi.Athomo ea boron e ka kenya letsoho litšebelisanong le li-biomolecules, tse kang nucleic acid kapa liprotheine, 'me e 'nile ea hlahlojoa bakeng sa ho fana ka lithethefatsi tse lebisitsoeng, ho ntlafala ha lisele tsa cellular, kapa ho lokolloa ho laoloang ha mekhoa ea phekolo.Ka kakaretso, 4-Hydroxyphenylboronic acid pinacol ester e sebelisoang ho organic synthesis, lits'ebetso tsa ho utloa, le lits'ebetsong tsa phano ea lithethefatsi.Ts'ebetso ea eona ea boronic ester e e nolofalletsa ho nka karolo ho Suzuki-Miyaura cross-coupling reaction le ho etsa liphetoho tsa sehlopha se sebetsang, ho holisa ts'ebeliso ea eona ea maiketsetso.Ho feta moo, HBP ester e ka etsa li-complexes tse fetolehang tse nang le diol, e etsa hore e be ea bohlokoa bakeng sa nts'etsopele ea li-sensor tsa molek'hule.Bokhoni ba eona litsamaisong tsa phano ea lithethefatsi bo boetse bo totobatsa bohlokoa ba eona e le motsoako o sebetsang ka bongata mafapheng a fapaneng a saense le thekenoloji.
