Notes:
The formation and properties of silicon-phosphorus and aluminum-phosphorus compounds are described. Silylphosphines are decomposed solvolytically by H2O, C2H5OH, NH3, hydrogen halides, C2H5I, and boron halides at the Si—P bond; decomposition may be preceded by formation of an addition compound. Extensive side reactions during the reaction of halogenosilanes with LiPEt2The following abbreviations are used in this paper: Et = C2H5; Me = CH3; M = alkali metal (formation of Et2P—PEt2, HPEt2, Si-rich residues) are due to an excess of LiPEt2 in the reaction mixture. The reaction of LiPEt2 with AlCl3, AlHCl2, and AlH2Cl leads to definite aluminum-phosphorus compounds if only one PEt2 group is present per Al atom, e.g. in (Cl2Al-PEt2)3, or if salts such as Li[Al(PEt2)4] and Li[AlH2(PEt2)2] can be formed with an excess of LiPEt2.
