Transient Infrared-Spectroscopy of (Eta(5)-C-5-H-5)Co(Co)(2) Photoproduct Reactions in Hydrocarbon Solutions
Ultrafast photochemistry of CpCo(CO)(2) in n-hexane, 1-hexene, and solvent mixtures (298 K) are reported. Multichannel infrared spectra (0.4 ps, 4 cm(-1) resolution) identify the vibrational cooling of CpCo(CO)(n-hexane) and CpCo(CO)(1-hexene). The conversion rate of transient n-hexane species to stable l-hexene product for 0.2-2.0 mol/liter 1-hexene/n-hexane solutions (k = 1.4 +/- 0.2 X 10(10) M(-1) s(-1)) was determined.
