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

Ulwazi

I-Benzyltriphenylphosphine bromide yi-organic phosphorus compound. Isisiqina esimhlophe esinyibilikayo kwizinyibilikisi zendalo ezifana nebenzene kunye nedichloromethane, kodwa azinyibiliki emanzini.

I-Benzyltriphenylphosphine bromide inezicelo ezibalulekileyo kwi-organic synthesis. Inokuthi isebenze njenge-nucleophile kwaye ithathe inxaxheba kwiimpendulo ezifana ne-chlorination, bromination, kunye ne-sulfonylation. Isenokusetyenziswa njengomthombo we-phosphine ukuthatha inxaxheba kwiimpendulo ze-phosphine, ezifana ne-synthesis of fullerenes. Inokusetyenziswa kwakhona njenge-ligand ye-catalysts, ifom ye-complexes enezinyithi zenguqu, ithathe inxaxheba kwiimpendulo ze-organic synthesis, njalo njalo.

Indlela yokulungiselela i-benzyl triphenylphosphine bromide inokufunyanwa ngokusabela kwi-benzene bromide, i-triphenylphosphine, kunye ne-benzyl bromide, kwaye iimeko zokusabela ziqhele ukwenziwa kwiqondo lobushushu begumbi.

Ulwazi ngokhuseleko: I-Benzyltriphenylphosphine bromide iyacaphukisa kwaye inokubangela ukucaphuka kwamehlo, ulusu kunye nenkqubo yokuphefumla. Amanyathelo afanelekileyo okukhusela kufuneka anxitywe ngexesha lokusetyenziswa, njengokunxiba izibuko ezikhuselayo, iiglavu, kunye nesixhobo sokuphefumla. Zigcine kude nobushushu kunye nemithombo yomlilo, gcina kwindawo engena umoya, kwaye uphephe ukudibana nee-oxidants. Ukuba kukho ingozi, funa unyango ngokukhawuleza. Landela ngokungqongqo iinkqubo zokusebenza ezifanelekileyo zokhuseleko xa ubamba kwaye ugcina i-benzyltriphenylphosphine bromide.
