Selective loss of CO in the photochemistry of MnRe(CO)10: a study using matrix isolation and time-resolved infrared spectroscopy


Journal Article

Photolysis of MnRe(CO)10, in argon matrices or room temperature solution, causes dissociation of CO and the formation of a singly bridged intermediate, (CO)4Mn(μ-CO)Re(CO)4. The reaction has been studied using samples specifically enriched with 13CO on the Re end. Careful monitoring, by infrared spectroscopy, of the intensity ratio of 12CO/13/CO of free CO (matrix solution) and of the bridging band of (CO)4Mn(μCO)Re(CO)4 (matrix isolation and time-resolved infrared spectroscopy) show that CO is expelled only from the Mn end of the dimer. There is no evidence for rapid interchange between the bridging CO group and the terminal CO groups on the Mn ends of (CO)4Mn(μ-CO)Re(CO)4. © 1987.
