| Abstract: | Trichlorosilylated tetrelides (Cl3Si)3E]? have been prepared by adding 1 equiv of a soluble Cl? salt to (Cl3Si)4Si (E=Si) or 4 Si2Cl6/GeCl4 (E=Ge). To assess their donor qualities, the anions (Cl3Si)3E]? (E=C, Si, Ge) have been treated with BCl3, AlCl3, and GaCl3. Both BCl3 and GaCl3 give 1:1 adducts with the anionic centers. AlCl3 leads to Cl? abstraction from (Cl3Si)3E]? with formation of (Cl3Si)4E (E=Si or Ge). (Cl3Si)4Ge is cleanly converted to the perhydrogenated (H3Si)4Ge by use of LiAlH4]. Another case of Cl? abstraction was observed for (Cl3Si)3Ge ? GaCl3]?, which reacts with GaCl3 to afford the neutral dimer (Cl3Si)3Ge?GaCl2]2. |
