ABSTRACT:
Saturated hydrocarbon is transformed catalytically into olefinic hydrocarbon of corresponding skeletal configuration by reacting the saturated hydrocarbon with a suitable alkene cyclopentadienyl or alkene arene transition metal molecular complex, such as bis(ethylene)pentamethylcyclopentadienyliridium, in the presence of free alkene as hydrogen acceptor. The reaction may be performed photochemically under irradiation with ultraviolet light or it may be performed thermolytically under application of heat. The catalyst may be charged to the reaction as a preformed alkene cyclopentadienyl or alkene arene transition metal molecular complex or the catalyst may be formed in situ in the reaction mixture via displacement of ligand from a suitable transition metal complex containing the displaceable ligand, such as dicarbonylpentamethylcyclopentadienyliridium or cyclooctadienepentamethylcyclopentadienyliridium.
