Photochemistry of Fe2(CO)8(mu-CH2).
Abstract
We herein present the previously unreported photochemistry of two forms of the dimetallocyclopropane complex Fe2(CO)8(mu-CH2), and its deuterated analog. We have determined that it behaves similarly to other dimetallic carbonyls in that it eliminates carbon monoxide upon irradiation with high-intensity UV/visible light to form distinct single and double CO-loss products. Upon formation of a 34-electron single CO-loss product, however, it exhibits the ability to either maintain an unbalanced 16/18-electron configuration, or convert to a carbene complex with an iron-iron double bond. This unusual behavior is possibly due to the high degree of pi-interaction between the mu-CH2 ligand and the dimetallic center. There is also evidence that a solvento compound is being formed which could explain both the stability of the single CO-loss product and the apparent formation of Fe(CO)5 within the low-temperature matrix.
