Abstract
Dihalogermylenes, dihalostannylenes, and their complexes (EI2, ECl2·dioxane, and (CO)5W=ECl2·THF, where E = Ge or Sn), unlike organylgermylenes, are not inserted at the Si—H (Ge—H) bond of triethylsilane (triethylgermane). The reactions of SnI2, ECl2·dioxane, and (CO)5W=ECl2·THF (E = Ge or Sn) with Et3E"H (E" = Si or Ge) occur as redox processes. Depending on the nature of the reagents, the reactions afford products of oxidative coupling (Et3SiSiEt3) and/or haloiodination (Et3SiX and Et3GeX) of triethylsilane (triethylgermane). The proposed mechanism of these reactions involves the electron transfer to form radical-ion pairs.
