Evidence for the formation of free 16-electron species rather than solvate complexes in the ultraviolet irradiation of CpCo(CO){sub 2} in liquefied noble gas solvents
- Lawrence Berkeley Lab., CA (United States)
This paper describes a study of the photochemistry of CpCo(CO){sub 2} in liquid Kr and Xe in the presence of hydrocarbons in order to estimate directly the relative strengths of the CpCo(CO)-noble gas and CpCo(CO)-alkane interactions. However, it is seen in contrast with results for Cp{sup *}Rh(CO) and other coordinatively unsaturated organometallic complexes, CpCo(CO) and Cp{sup *}Co(CO) do not bind detectably to either noble gas atom or cyclohexane. The most surprising results is the observation that the rate of reaction between the monocarbonyl and dicarbonyl cobalt complexes is essentially unaffected by changing the solvent from liquid Kr to liquid Xe, adding cyclohexane or making the cyclopentadienyl ligand substantially more hindered. 22 refs., 2 figs.
