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

I-Diphenylphosphine oxide iyingxenye ebalulekile ye-organic synthesis esetshenziswa kabanzi ekuhlanganiseni izibulala-zinambuzane ezihlukahlukene kanye ne-chiral phosphine ligands, futhi ingangena esikhundleni se-alkali metal cyanides njengama-coupling agents we-heterocyclic compound synthesis, njengokuhlanganiswa okuncane kwe-herbicide paraquat.

Isicelo

I-Diphenylphosphine oxide ijwayele ukusetshenziswa ekulungiseni i-triphenylphosphine oxide, i-alkyne add, kanye nama-reagents okusabela e-Wittig Horner. Ukwenziwa kokuphuma kokuphuma kwe-diphenylphosphine kuhilela ukuhlangana kwe-Ph2P (O) H ne-trifluoromethanesulfonic acid i-aryl ester, kanye nokwehliswa kwe-phosphine oxide ukuze kutholwe i-diphenylarylphosphine, okuyi-chiral ligand evame ukusetshenziswa.
