Ein kationischer Rhodium(I)‐Komplex katalysiert die Titelreaktion von 1,6‐Diinen als [2+2+2]‐Cycloaddition und anschließende elektrocyclische Ringöffnung (siehe Schema; cod=1,5‐Cyclooctadien, H 8 ‐binap=2,2′‐Bis(diphenylphosphanyl)‐5,5′,6,6′,7,7′,8,8′‐octahydro‐1,1′‐binaphthyl). Die asymmetrische intramolekulare [2+2+2]‐Cycloaddition zwischen 1,3‐Dicarbonylverbindungen und 1,6‐Eninen gelang ebenfalls.
