Come on allene : The [{RhCl(CO) 2 } 2 ]‐ or [{RhCl(CO)dppp} 2 ]‐catalyzed intramolecular [5+2] cycloaddition of alkyne‐allenylcyclopropanes under mild conditions affords the bicyclo[5.4.0]undecatriene or the larger bicyclo[5.5.0]dodecatriene frameworks (see scheme; dppp=1,3‐bis(diphenylphosphino)propane).
