4-(2-hydroxypropan-2-yl)phenylboronic acid (CAS# 886593-45-9)

Isingeniso

I-4-(2-hydroxypropan-2-yl) i-phenylboronic acid iyinhlanganisela ye-organoboron. Ifomula yayo yamakhemikhali ithi C10H13BO3 futhi isisindo sayo samangqamuzana esihlobene singu-182.02g/mol.

Imvelo:

I-4-(2-hydroxypropan-2-yl) i-phenylboronic acid iyikristale eqinile emhlophe. Iyancibilika emanzini futhi iyancibilika kuzincibilikisi zemvelo. Inephuzu lokuncibilika eliphansi uma kuqhathaniswa futhi elibilayo, elincibilika cishe ku-100-102°C. Kuyinhlanganisela ezinzile engafakwa i-oxid noma ukubola kalula.

Sebenzisa:

I-4-(2-hydroxypropan-2-yl) i-phenylboronic acid iyi-reagent ebalulekile ku-organic synthesis. Ingasetshenziswa ekuhlanganiseni kwe-phenylboronic acid ukwenza izibopho ze-carbon-boron ngokusabela ngezinhlanganisela ze-organometallic ukwakha izakhiwo eziyinkimbinkimbi ze-organic molecule. Ingase futhi isetshenziswe njenge-catalyst ligand ukubamba iqhaza ekuphenduleni okuhlukahlukene kwe-organic synthesis njengokusabela kwe-redox, ukusabela okuhlangene, kanye nokuhlangana kwe-cross-coupling.

Indlela Yokulungiselela:

I-4-(2-hydroxypropan-2-yl) i-phenylboronic acid ingalungiswa ngokusabela kwe-phenylboronic acid kanye ne-2-hydroxypropane. Indlela yokulungiselela evame ukusetshenziswa ukusabela nge-phenylboronic acid ne-2-hydroxypropanol ngaphansi kwezimo ze-alkali ukukhiqiza umkhiqizo ohlosiwe, ohlanjululwa nge-crystallization ukuze uthole umkhiqizo ohlanzekile.

Ulwazi Lokuphepha:

I-4-(2-hydroxypan-2-yl) i-phenylboronic acid iphephile uma kuqhathaniswa ngaphansi kwezimo ezijwayelekile zokusetshenziswa. Kodwa-ke, njenganoma iyiphi ikhemikhali, kufanele unake izinyathelo zokuphatha eziphephile, ugweme ukuthinta isikhumba, amehlo nomlomo, futhi ugweme ukuhogela uthuli noma umhwamuko waso. Gqoka amagilavu ​​okuzivikela, izibuko nezingubo zokuzivikela ngesikhathi sokusebenzisa. Uma uthintwa noma uhogelwe, geza indawo ethintekile ngokushesha futhi ufune iseluleko sezokwelapha.
