The photochemical reaction of tricarbonyl-η6-1,3,5-cycloheptatriene-chromium(0) (I) with tricyclo[6.3.0.02,7]undeca-3,5-diene (II) in n-pentane at 248 K yields the [4 + 6]-cycloadduct tricarbonyl-η6-pentacyclo[7.6.2.110,15.02,8.03,7]octadeca-11,13,16-triene-chromium(0) (III). Detachment of the pentacyclic triene ligand from chromium can be achieved with trimethylphosphite. The constitutions of complex III and of the pentacyclic hydrocarbon IV were determined by spectroscopic means.
