Os(PHPh)Cl(CO)2(PPh3)2 gives [OsCl(PHIPh)(CO)2(PPh3)2]+ and deprotonation of this cation affords Os(PIPh)Cl(CO)2(PPh3)2. The iodophenylphosphido complex reacts with AgSbF6 in THF/MeOH to give [OsCl[PH(OMe)Ph>](CO)2(PPh3)2]SbF6 suggesting the intermediacy of a phenylphosphinidene complex [Os(=PPh)Cl(CO)2(PPh3)2]+.
将I 2添加到Os(
PHPh)Cl(CO)2(PPh 3)2中得到[OsCl(PHIPh)(CO)2(PPh 3)2 ] +,该阳离子的去质子化得到Os(
PIPh)Cl(CO)2(PPh 3)2。
碘代
苯基膦酸酯配合物与AgSbF 6在THF / MeOH中反应生成[OsCl [PH(OMe)Ph>](CO)2(PPh 3)2 ] SbF 6,表明苯基
次膦酸酯配合物[Os(= PPh)Cl( CO)2(PPh 3)2 ] +。
