I-Benzyltriphenylphosphonium bromide (CAS# 1449-46-3)

Ulwazi

I-Benzyltriphenylphosphine bromide iyinhlanganisela ye-organic phosphorus. Iqinile emhlophe encibilika kuzincibilikisi zemvelo njenge-benzene ne-dichloromethane, kodwa ayincibiliki emanzini.

I-Benzyltriphenylphosphine bromide inezinhlelo zokusebenza ezibalulekile ku-organic synthesis. Ingasebenza njenge-nucleophile futhi ibambe iqhaza ekuphenduleni okufana ne-chlorination, i-bromination, ne-sulfonylation. Ingasetshenziswa futhi njengomthombo we-phosphine ukuze ubambe iqhaza ekuphenduleni kwe-phosphine, njengokuhlanganiswa kwama-fullerenes. Ingasetshenziswa futhi njenge-ligand yama-catalysts, yakha ama-complexes anezinsimbi eziguqukayo, iqhaza ekuphenduleni kwe-organic synthesis, njalonjalo.

Indlela yokulungiselela ye-benzyl triphenylphosphine bromide ingatholwa ngokusabela kwe-benzene bromide, i-triphenylphosphine, ne-benzyl bromide, futhi izimo zokusabela ngokuvamile zenziwa ekamelweni lokushisa.

Ulwazi lokuphepha: I-Benzyltriphenylphosphine bromide iyacasula futhi ingase ibangele ukucasuka emehlweni, isikhumba, kanye nesistimu yokuphefumula. Izinyathelo zokuzivikela ezifanele kufanele zigqokwe ngesikhathi sokusetshenziswa, njengokugqoka izibuko ezivikelayo, amagilavu, kanye nomshini wokuphefumula. Ziqhelelanise nemithombo yokushisa neyomlilo, gcina endaweni engenawo umoya, futhi ugweme ukuthintana nama-oxidants. Uma kwenzeka ingozi, funa usizo lwezokwelapha ngokushesha. Landela ngokuqinile izinqubo zokusebenza zokuphepha ezifanele lapho uphatha futhi ugcina i-benzyltriphenylphosphine bromide.
