Silylgermylpotassium Compounds

Abstract

By the reactions of potassium tert-butoxide with a number of oligosilylgermanes, oligosilylgermylpotassium compounds were generated. Their chemistry very much resembles that of the analogous oligosilylsilylpotassium compounds. However, the ease of formation is even more pronounced in the case of the germyl anions. Again potassium tert-butoxide proved to be a highly selective metalation reagent, leading to no unwanted cleavage of Si−Ge or Ge−Ge bonds. A number of new and potentially useful oligosilylgermyl mono- and dianions have been prepared in this manner.
