Iyini i-Diphenylphosphine oxide CAS 4559-70-0?

I-Diphenylphosphine oxide iyindlela ebalulekile yokwenziwa kwezinto eziphilayo esetshenziswa kabanzi ekwakhiweni kwezibulala-zinambuzane ezahlukahlukene kanye nama-chiral phosphine ligands, futhi ingathatha indawo ye-alkali metal cyanides njengezinto zokuhlanganisa zokwenziwa kwe-heterocyclic compound, njengokwenziwa okuncane kwe-herbicide paraquat.

Isicelo

I-Diphenylphosphine oxide ivame ukusetshenziswa ekulungiseleleni i-triphenylphosphine oxide, i-alkyne addition, kanye nama-reagents okusabela e-Wittig Horner. Ukwenziwa kwe-diphenylphosphine derivatives kuhilela ukuhlanganiswa kwe-Ph2P (O) H ne-trifluoromethanesulfonic acid aryl ester, kanye nokunciphisa i-phosphine oxide ukuze kutholakale i-diphenylarylphosphine, okuyi-chiral ligand esetshenziswa kakhulu.
