Reaction of a diaryldigermyne with ethylene
Access this Article
Reaction of the stable digermyne BbtGeGeBbt (Bbt = 2, 6-[CH(SiMe<inf>3</inf>)<inf>2</inf>]<inf>2</inf>-4-[C(SiMe<inf>3</inf>)<inf>3</inf>]-C<inf>6</inf>H<inf>2</inf>) 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.
