Diphenylphosphine oxide CAS 4559-70-0
ʻO ka diphenylphosphine oxide kahi mea koʻikoʻi koʻikoʻi synthesis intermediate i hoʻohana nui ʻia i ka synthesis o nā pesticides like ʻole a me nā ligands chiral phosphine, a hiki ke hoʻololi i nā cyanides metala alkali e like me nā mea hoʻohui no ka heterocyclic compound synthesis, e like me ka synthesis māmā o herbicide paraquat.

Hoʻohana mau ʻia ka diphenylphosphine oxide i ka hoʻomākaukau ʻana i ka triphenylphosphine oxide, alkyne hoʻohui, a me Wittig Horner reaction reagents. ʻO ka synthesis o nā derivatives diphenylphosphine e pili ana i ka hoʻohui ʻana o Ph2P (O) H me ka trifluoromethanesulfonic acid aryl ester, a me ka hoʻemi ʻana o ka phosphine oxide e loaʻa ai ka diphenylarylphosphine, ʻo ia ka ligand chiral maʻamau.
Hoʻopili pinepine ʻia i ka 25kg / pahu, a hiki ke hana ʻia i ka pōʻai maʻamau.
