UV photolysis of (η4-2,3-dimethylbutadiene)Fe(CO)3 and (η4-butadiene)Fe(CO)3 in inert matrices at 10 K was monitored by IR and UV spectroscopy. Elimination of CO is the predominant photoreaction. In the latter case we also observed the decomplexation of the butadiene ligand and hence the formation of (η2-butadiene)Fe(CO)3. This product is also obtained during the photolysis of (η2-butadiene)Fe(CO)4 which is subsequently transformed to (η4-butadiene)Fe(CO)3. For comparison, (η2-ethylene)Fe(CO)4 and (η2-1,3-cyclohexadiene)Fe(CO)4 were photolyzed under analogous conditions. Photolysis of (η4-1,3-diene)Fe(CO)3 complexes in nitrogen matrices gives (η4-1,3-diene)Fe(CO)2N2; formation of (η2-butadiene)Fe(CO)3N2 from (η2-butadiene)Fe(CO)4 requires annealing of the nitrogen matrix subsequent to irradiation.
