Taupānga

Ko te diphenylphosphine oxide te nuinga o te wa e whakamahia ana i roto i te whakaritenga o te waikura triphenylphosphine, te taapiri alkyne, me nga reagents tauhohenga Wittig Horner. Ko te whakahiatotanga o te diphenylphosphine derivatives ko te hono o te Ph2P (O) H me te trifluoromethanesulfonic acid aryl ester, me te whakahekenga o te phosphine oxide ki te whiwhi i te diphenylarylphosphine, he roopu chiral e whakamahia nuitia ana.
