Triphenylphosphine: xubin ka mid ah fosfiinnada saddexaad
Triphenylphosphine (TPP) waa xubin ka mid ah fosfiinnada saddexaad, kaas oo ah fosfiin, kaas oo saddexda haydarojiin lagu beddelo kooxaha phenyl. Waxay leedahay door ah wakiil yareeya iyo isku-darka tixraaca isbeddelka kiimikada NMR. Waa ligand muhiim ah oo loo isticmaalo falgalka Wittig ee isku-darka alkene. Falcelintani waxay ku lug leedahay sameynta alkyliden-etriphenylphosphoranes laga bilaabo ficilka butyllithium ama saldhig kale oo ku yaal halide rubuca. Triphenylphosphine waxaa loo isticmaalaa in lagu sameeyo isku-darka walxaha dabiiciga ah sababtoo ah nucleophilicity iyo dabeecadda yaraynta.

Isticmaalka
Triphenylphosphine waxaa marka hore lagu daraa sulfonate iyadoo la adeegsanayo oleum si loo sameeyo trisulfonic acid.
Triphenylphosphine waxaa loo isticmaali karaa isku-darka Wittig. Waa ligand caadi ah oo ku jira isku-darka isku-dhafan.
Triphenylphosphine waxaa loo isticmaalaa isku-darka organophosphorus intermediate, trimethyl phosphite ee habka is-weydaarsiga ester. Kadibna waxaa si dheeraad ah loo heli karaa taxane ah sunta cayayaanka ee organophosphorus sida dichlorvos, monocrotophos iyo phosphamidon.
Intaa waxaa dheer, waxaa loo isticmaali karaa sidii xasiliyayaal isku-darka cinjirka iyo resin-ka, antioxidants-ka ku jira polyvinyl chloride, iyo walxo cayriin ah oo ku jira isku-darka resin-ka alkyd iyo resin-ka polyester-ka.
