5-methoxybenzofuran-2-ylboronic acid (CAS# 551001-79-7)

Isingeniso

I-Benzonium, eyaziwa nangokuthi i-5-methoxybenzofuran-2-ylboronic acid, iyinhlanganisela yezinto eziphilayo. Inefomula yamangqamuzana engu-C9H9BO4 kanye nesisindo samangqamuzana esingu-187.98g/mol.

Imvelo:

-Ukubukeka: i-asidi iqinile engenambala ukuya kokuphuzi ngokukhanyayo.

-I-Solubility: Incibilika kwezinye izinyibilikisi zemvelo, njenge-dimethyl sulfoxide (DMSO), i-dichloromethane ne-ethanol.

Sebenzisa:

i-asidi iyindawo ebalulekile ephakathi ku-organic synthesis futhi ivame ukusetshenziselwa ukwakha izinhlanganisela ze-benzofuran. Ingasetshenziswa njenge-reagent emkhakheni wokuhlanganiswa kwezidakamizwa, ukuhlanganiswa kwamakhemikhali kanye nesayensi yezinto ezibonakalayo.

Indlela Yokulungiselela:

Ukulungiswa kwe-Cr acid kuvame ukutholwa ngokusabela kwe-benzofuran compounds ne-aldehyde borate. Izinyathelo eziqondile zifaka phakathi ukusabela kwinhlanganisela ye-benzofuran nge-aldehyde borate ku-toluene noma i-dimethyl sulfoxide, nokukhuthaza ukusabela ngokufudumeza nokungeza i-catalyst.

Ulwazi Lokuphepha:

Njengoba lungekho ulwazi oluningiliziwe lwezokuphepha olubikiwe esidlangalaleni, kuyadingeka ukuthi kulandelwe izinqubo ezijwayelekile zokuphepha zaselabhorethri lapho usebenzisa futhi uphatha inhlanganisela, okuhlanganisa ukugqoka amagilavu ​​aselabhorethri, izibuko zokuzivikela nezingubo zokuzivikela. Ngesikhathi esifanayo, kuyadingeka ukuthi usebenze endaweni enomoya omuhle futhi ugweme ukuthintana nesikhumba, ukuphefumula noma ukungenisa. Uma kwenzeka ukuthintana ngokungafanele, hlambulula ngokushesha ngamanzi amaningi futhi ufune usizo lwezokwelapha. Qaphela imithetho yendawo lapho ulahla.
