The Formation of Disilylphosphino-Element Compounds of C, Si, P The reactions of (me3Si)2PLi · OR2 a (OR2 = 1 monoglyme or 2 THF; me = CH3) with CH3Cl, CH2Cl2, ClCH2CH2Cl and ClCH2? C6H5 give the compounds (me3Si)2Pme, (me3Si)2P? CH2? P(Sime3)2, (me3Si)2P? CH2CH2Cl, (me3Si)2P? CH2CH2? P(Sime3)2 and (me3Si)2P? CH2C6H5 respectively. In the same manner a reacts with me2SiCl2 in a molar ratio 1:1 to (me3Si)2P? Sime2Cl and in a molar ratio 2:1 to (me3Si)2P? Sime2? P(Sime3)2 b . The compound b decomposes to [me3SiP? Sime2]2 and (me3Si)3P at 220°C. In the reactions of a with ClP(C6H5)2 and ClPme2 the compounds (me3Si)2P? P(C6H5)2 and (me3Si)2P? Pme2, respectively, are obtained. a reacts with HgCl2 to (me3Si)2P? P(Sime3)2. (me3Si)3P can be cleaved with ClP(C6H5)2 and ClPme2 yielding (me3Si)2P? P(C6H5)2 and (me3Si)2P? Pme2, respectively. The 1H- and 31P-n.m.r. and mass spectroscopic data are reported. |
