Synthesis of Triple-bonded Compounds Derived from Trianion Species of Heavier Group 14 Elements and their Application to Polymers

三碲基硅烷、三甲硅基硅烷和三甲硅基锗烷的金属转移反应得到相应的单锂硫物种。对三甲硅基锡烷的金属转移反应进行了重新研究，得到了锂锡烷，其令人惊讶地作为三阴离子等价物反应。锗烷锂衍生的锗酰二氯膦与叔丁醇钾反应生成磷锗-亚乙烯基二聚体，表明形成了中间体锗-磷三键化合物。

Transmetalation reactions of tritellurosilane, trisilylsilane and trisilylgermane afforded the corresponding monolithio species. Reinvestigation on the transmetalation reaction of trisilylstannane provided lithiostannane, which surprisingly reacted as a trianion equivalent. Germyldichlorophosphine derived from lithiogermane reacted with potassium t-butoxide to afford phosphagermavinylidene dimer, suggesting that formation of an intermediary germanium-phosphorus triple-bonded compound.
