Abstract

Reaction of the stable digermyne BbtGe[triple bond, length as m-dash]GeBbt (Bbt = 2,6-[CH(SiMe)]-4-[C(SiMe)]-CH) with ethylene initially afforded the corresponding 1,2-digermacyclobutene. Depending on the reaction conditions applied, further reaction of this 1,2-digermacyclobutene with ethylene furnished two different reaction products: a 1,4-digermabicyclo[2.2.0]hexane or a bis(germiranyl)ethane. Combined experimental and theoretical results suggested that the 1,4-digermabicyclo[2.2.0]hexane and the bis(germiranyl)ethane are the thermodynamic and kinetic reaction products, respectively. A reaction mechanism in agreement with these results was proposed.

摘要

稳定的二锗炔BbtGe≡GeBbt（Bbt = 2,6-[CH(SiMe)]-4-[C(SiMe)]-CH）与乙烯反应，最初生成相应的1,2-二锗环丁烯。根据所采用的反应条件，该1,2-二锗环丁烯与乙烯的进一步反应产生了两种不同的反应产物：1,4-二锗双环[2.2.0]己烷或双（锗亚烷基）乙烷。实验和理论相结合的结果表明，1,4-二锗双环[2.2.0]己烷和双（锗亚烷基）乙烷分别是热力学和动力学反应产物。提出了与这些结果一致的反应机理。
