A straightforward synthesis of tetra-and trialkynylgermanes by reactions of compounds containing Ge-N or Ge-Cl bonds with alk-1-ynes was proposed. Reactions of appropriate amino-or halogermanes with alk-1-ynes were effective only in the presence of an equivalent amount of zinc dihalide.
通过含有 Ge-N 或 Ge-Cl 键的化合物与烷基-1-炔的反应,提出了一种直接合成四炔基
锗和三炔基
锗的方法。只有在等量的二卤化
锌存在下,适当的
氨基或卤代
锗与烷-1-炔的反应才有效。
