摘要

Triphenylcyclopropene is converted to hexaphenylbenzene on treatment with potassium amide in liquid ammonia, but with sodium amide or lithium amide a simple dimer can be intercepted, triphenylcyclopropyltriphenylcyclopropene (Ia). This dimer is also formed when triphenylcyclopropene is heated in refluxing xylene. Treatment of the dimer with potassium amide converts it to hexaphenylbenzene, while pyrolysis of the dimer at 280'affords ...
