Daim ntawv thov

Diphenylphosphine oxide feem ntau yog siv rau hauv kev npaj ntawm triphenylphosphine oxide, alkyne ntxiv, thiab Wittig Horner cov tshuaj tiv thaiv. Kev sib txuas ntawm diphenylphosphine derivatives koom nrog kev sib txuas ntawm Ph2P (O) H nrog trifluoromethanesulfonic acid aryl ester, thiab txo cov phosphine oxide kom tau txais diphenylarylphosphine, uas yog ib qho kev siv chiral ligand.
