| Research Abstract |
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.
