(Me3Si)2CHP(O)(OMe)2. Reaction of II with LiAlH4 gave TpsiPH2, and reaction of I with NaBH4 gave the adduct TsiPH2 · BH3. The identity of II has been confirmed by an X-ray diffraction study which shows that the crystals consist of discrete molecules with PCl 2.087(9) Å and ClPCl 96.1(1)°.
通过TsiLi或TpsiLi与TsiLi或TpsiLi的反应获得了化合物TsiPCl 2(Tsi =(Me 3 Si)3 C)(I)和TpsiPCl 2(Tpsi = [(PhMe 2 Si)3 C])(II)。 PCl 3。在TsiLi的情况下,可以改变反应条件,从而获得50%的
二膦TsiP
PTsi代替化合物I。TsiLi与PBr 3的反应主要产生TsiBr和少量的TsiPBr 2,但获得后者通过用BBr 3处理I可以高产。TpsiLi不与PPh 2 Cl反应,但与PPhCl 2反应得到TpsiCl。TsiLi与P(O)Cl 3反应得到TsiCl。卤化物TsiX和TpsiX(X = Cl或Br)大约在大约5分钟内制成。TsiLi或TpsiLi和卤化物CX 4的收率为50%。用P(OMe),TsiLi产生的TsiMe收率好于TsiP(OMe)2,但后者是通过用含NaOMe的MeOH处理I
