| Abstract: | Formation of Organosilicon Compounds. 99. Separation of Carbosilane and Silylphosphane Mixtures by Means of HPLC Test mixtures of Si-methylated carbosilanes were separated by means of reversedphase HPLC (nucleosil 5-C18; CH3OH:hexane = 90:10). The corresponding SiCl-containing mixtures were successfully separated only after reductin of the SiCl groups by means of LiAlH4 (CH3OH: C6H6 + H2O = 92.5:7.5 + 4—8%). A model separation of the silylphosphanes Me3SiPH2, (Me3Si)2PH and (Me3Si)3P using the same material but acetonitrile: toluene = 85:15 is also reported. |
