Hexafluoroacetone reacts with PH3 and MePH2 under insertion into the PH bond yielding either H2PC(CF3)2OH and HP[C(CF3)2OH]2 or Me(H)PC(CF3)2OH and MeP[C(CF3)2OH]2 whereas Me2PH gives a mixture of Me2P(F)[OCH(CF3)2]2, Me2PPMe2, and Me2P(O)OCH(CF3)2. Me3P forms a dialkoxyphosphorane if there is a 1:2 ratio (Me3P:(CF3)2CO). H2PC(CF3)2OH and HP[C(CF3)2OH]2 are easily O-silylated to give H2PC(CF3)2OSiMe3
六氟丙酮在插入PH键中时与PH 3和MePH 2反应,生成H 2 PC(CF 3)2 OH和HP [C(CF 3)2 OH] 2或Me(H)PC(CF 3)2 OH和MeP [C(CF 3)2 OH] 2,而Me 2 PH给出了Me 2 P(F)[OCH(CF 3)2 ] 2,Me 2 PPMe 2和Me 2 P(O)OCH的混合物(CF 3)2。如果比例为1:2(Me 3 P:(CF 3)2 CO),则Me 3 P形成二烷氧基磷烷。H 2 PC(CF 3)2 OH和HP [C(CF 3)2 OH] 2易于O硅烷化,得到H 2 PC(CF 3)2 OSiMe 3和HP [C(CF 3)2 OSiMe 3 ] 2。单硅烷化的化合物在PC键断裂的情况下被氯(溴)氧化,从而提供PCl 3(PBr 3),(CF 3)2 CO和Me 3 SiCl(Me 3 SiBr)。使用N-氯(溴)琥珀酰亚胺
