I-Triphenylphosphine: ilungu le-tertiary phosphines
I-Triphenylphosphine (TPP) lilungu le-tertiary phosphines, eyi-phosphane, apho ii-hydrogen ezintathu zithathelwa indawo ngamaqela e-phenyl. Inendima njenge-reducing agent kunye ne-NMR chemical shift reference compound. Yi-ligand ebalulekileyo esetyenziswa kwi-Wittig reaction yokwenza i-alkene. Le reaction ibandakanya ukwakheka kwe-alkyliden-etriphenylphosphoranes ngenxa yesenzo se-butyllithium okanye esinye isiseko kwi-quarternary halide. I-Triphenylphosphine isetyenziselwa ukwenza ii-organic compounds ngenxa ye-nucleophilicity yayo kunye nohlobo lwayo lokunciphisa.

Ukusetyenziswa
I-Triphenylphosphine iqala ngokufakwa i-oleum kwi-sulfonation ukuze yenze i-trisulfonic acid.
I-Triphenylphosphine ingasetyenziswa kwi-Wittig synthesis. Yi-ligand eqhelekileyo kwi-catalysis efanayo.
I-Triphenylphosphine isetyenziswa ekuqulunqweni kwe-organophosphorus intermediate, i-trimethyl phosphite ngendlela yokutshintshiselana nge-ester. Emva koko uthotho lwezibulali zinambuzane ze-organophosphorus ezifana ne-dichlorvos, i-monocrotophos kunye ne-phosphamidon zinokufunyanwa ngakumbi.
Ukongeza, ingasetyenziswa njengeziqinisi ekuhlanganiseni irabha kunye neeresini, ii-antioxidants kwi-polyvinyl chloride, kunye nezinto eziluhlaza ekuhlanganiseni iiresini ze-alkyd kunye neeresini ze-polyester.
