Kev tshawb pom ntawm 2-bromophenylboronic acid tuaj yeem taug qab rov qab mus rau lub xyoo pua 20th, thaum chemists pib muaj kev txaus siab rau kev sib txuas thiab siv cov organic boron compounds. Nyob rau hauv 1903, German chemist Alfred Tshuag thawj synthesized phenylboronic acid thiab ua ntej kev tshawb fawb ntawm nws cov khoom. Qhov kev tshawb pom no tau tsim lub hauv paus rau kev tshawb fawb ntxiv ntawm 2-bromophenylboronic acid. Txawm li cas los xij, nws tsis yog txog xyoo 1950 uas cov qauv tshwj xeeb ntawm 2-bromophenylboronic acid tau maj mam nthuav tawm.
Xyoo 1954, American chemist Herbert C. Brown tau ua tiav synthesized 2-bromophenylboronic acid thawj zaug thaum kawm txog cov tshuaj tiv thaiv ntawm cov organic boron compounds. Brown tau txais cov qauv siv lead ua ntawm 2-bromophenylboronic acid los ntawm kev ua rau nws nrog tus neeg sawv cev brominating, thiab txiav txim siab nws cov qauv molecular siv X-ray diffraction technology. Qhov kev tshawb pom no tsis yog tsuas yog lees paub qhov muaj nyob ntawm 2-bromophenylboronic acid, tab sis kuj muab cov pov thawj tseem ceeb rau kev tshawb fawb txog cov organic boron chemistry.
Nyob rau xyoo 1960 thiab 1970s, nrog rau kev nce qib ntawm kev tshuaj ntsuam xyuas xws li nuclear magnetic resonance (NMR) thiab infrared spectroscopy (IR), cov kws tshawb fawb tau nkag siab tob txog cov qauv thiab cov khoom ntawm 2-bromophenylboronic acid. Xyoo 1967, British chemist Geoffrey Wilkinson tau soj ntsuam ntxiv txog qhov stereoisomerism ntawm 2-bromophenylboronic acid siv NMR thev naus laus zis, nthuav tawm nws cov khoom siv hluav taws xob thiab kev teeb tsa ntawm qhov chaw nyob hauv cov molecule. Cov kev tshawb fawb no tau tso lub hauv paus theoretical rau kev sib txuas thiab siv 2-bromophenylboronic acid.
2-Bromophenylboronic acid, nrog rau cov mis molecular C₆H₆BBrO₂ thiab molecular hnyav 200.83, yog ib qho tseem ceeb heev aromatic boronic acid derivative, uas nws cov tshuaj muaj pes tsawg leeg yog txiav txim siab los ntawm nws cov cim molecular qauv- muaj ib tug boronic acid pawg B ({{4} ₆B) txuas rau ortho- txoj hauj lwm ntawm lub nplhaib bromophenyl. Nws yog xim dawb los tawm -dawb crystalline hmoov nyob rau hauv ib txwm kub thiab siab, nrog lub melting point ntawm 110-114℃thiab solubility tsawg nyob rau hauv non-polar solvents xws li roj av ether, thaum nyob rau hauv me ntsis soluble nyob rau hauv polar solvents xws li methanol, ethanol, thiab tetrahydrofuran nyob rau hauv dej.
Cov cuab yeej tshuaj lom neeg tseem ceeb tshaj plaws yog qhov ua haujlwm ntawm nws pawg boronic acid. Zoo ib yam li lwm cov arylboronic acids, nws yooj yim tsim cyclic boroxines los ntawm lub cev qhuav dej condensation nyob rau hauv cua sov los yog acidic tej yam kev mob, thiab muaj peev xwm reversibly react nrog diols (xws li catechol thiab ethylene glycol) kom tsim tau ruaj khov cyclic boronic esters, ib tug yam ntxwv dav siv nyob rau hauv nws purification thiab structuralid. Nws tsis muaj zog acidic, nrog tus nqi pKa ntawm kwv yees li 8.8, muaj peev xwm ua haujlwm nrog cov hauv paus muaj zog (xws li sodium hydroxide) los ua dej -soluble boronate ntsev, thaum tseem nyob ruaj khov nyob rau hauv me ntsis acidic tej yam kev mob.
Lub bromine atom ntawm lub nplhaib benzene, raws li ib qho hluav taws xob - tshem tawm pawg, txo cov electron ceev ntawm lub nplhaib benzene, me ntsis tsis muaj zog ntawm nucleophilic hloov reactivity ntawm pawg boronic acid tab sis txhim kho nws ruaj khov nyob rau hauv oxidative ib puag ncig. Nws yog ib qho ruaj khov nyob rau hauv ib txwm cia tej yam kev mob, tab sis rhiab heev rau kub thiab muaj zog oxidants, uas yuav ua rau decomposition. Qhov tseem ceeb, nws tau txais txiaj ntsig zoo Suzuki-Miyaura hla- sib txuas cov tshuaj tiv thaiv nrog aryl halides hauv qab palladium catalysis, tsim cov pa roj carbon-carbon bonds, uas yog daim ntawv thov tseem ceeb-raws li cov khoom siv tshuaj lom neeg uas ua rau nws tseem ceeb hauv cov organic synthesis.
