Kodi Diphenylphosphine oxide CAS 4559-70-0 ndi chiyani?

Diphenylphosphine okusayidi ndi yofunika organic kaphatikizidwe wapakatikati chimagwiritsidwa ntchito kaphatikizidwe zosiyanasiyana mankhwala ndi chiral phosphine ligands, ndipo akhoza m'malo alkali zitsulo cyanides monga coupling agents kwa heterocyclic pawiri kaphatikizidwe, monga wofatsa synthesis wa herbicide paraquat.

Kugwiritsa ntchito

Diphenylphosphine oxide imagwiritsidwa ntchito popanga triphenylphosphine oxide, alkyne kuwonjezera, ndi Wittig Horner reaction reagents. Kaphatikizidwe ka zotumphukira za diphenylphosphine kumaphatikizapo kuphatikiza kwa Ph2P (O) H ndi trifluoromethanesulfonic acid aryl ester, komanso kuchepetsa phosphine oxide kuti apeze diphenylarylphosphine, yomwe imagwiritsidwa ntchito kwambiri chiral ligand.
