Flash and continuous photolysis studies of (μ-pdt)[Fe (CO) 3] 2 under excess CO were
conducted in coordinating and noncoordinating solvents. The back-reaction of CO with the
photoproduct showed second-order kinetics with k CO values of 1.0× 108, 3.4× 106, 1.2×
106, and 0.90 M–1 s–1 in hexanes, benzene, toluene, and THF, respectively. These data
indicate a solvent-coordinated intermediate as one photoproduct, but other long-lived
species were also apparent.
