Triphenylphosphine: nhengo yetertiary phosphines
Triphenylphosphine (TPP) inhengo yetertiary phosphines, inova phosphane, umo mahydrogen matatu anotsiviwa nemapoka ephenyl. Ine basa rekuderedza uye NMR chemical shift reference compound. I ligand yakakosha inoshandiswa muWittig reaction yekugadzira alkene. Kuita uku kunosanganisira kuumbwa kwealkyliden-etriphenylphosphoranes kubva pakuita kwebutyllithium kana imwe base pane quarternary halide. Triphenylphosphine inoshandiswa kugadzira organic compounds nekuda kwe nucleophilicity yayo uye hunhu hwekuderedza.

Kushandiswa
Triphenylphosphine inotanga yaiswa sulfonate neoleum kuti igadzire trisulfonic acid.
Triphenylphosphine inogona kushandiswa mukugadzira Wittig. Ndiyo ligand yakajairika mu catalysis yakafanana.
Triphenylphosphine inoshandiswa mukugadzirwa kwechinhu chinoshandiswa pakugadzira organophosphorus, trimethyl phosphite nenzira yekuchinjana ester. Uye zvino mishonga yezvipembenene inonzi organophosphorus yakadai sedichlorvos, monocrotophos uye phosphamidon inogona kuwanikwa zvakare.
Pamusoro pezvo, inogona kushandiswa sezvinodzivirira mukugadzirwa kwerabha nemaresini, maantioxydants mu polyvinyl chloride, uye zvinhu zvisina kugadzirwa mukugadzirwa kwealkyd resins nemaresini e polyester.
