苄基二羰基铁络合物（2）的辐射导致FeC键的溶血性断裂。在活化烯烃的存在下，发生自由基加成并形成饱和和不饱和加成产物7-9。在丙烯腈存在下，烷基铁配合物2、3和20的光解产生与相应酰基铁配合物28-30的辐照相同的产物。这表明，在光解条件下，烷基和酰基络合物彼此平衡。
Irradiation of benzyldicarbonyl(η5-cyclopentadienyl)iron complex (2) leads to hemolytic cleavage of the FeC bond. In the presence of activated alkenes, radical addition occurs and both saturated and unsaturated addition products 7–9 are formed. Photolysis of alkyliron complexes 2,3 and 20 in the presence of acrylonitrile leads to the same products as the irradiation of the respective acyliron complexes 28–30. This indicates that, under photolytical conditions, alkyl and acyl complexes are in equilibrium with each other.
