Flash and continuous photolysis kinetic studies of the iron-iron hydrogenase model (μ-pdt)[Fe(CO)3]2 in different solvents.
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 × 10(8), 3.4 × 10(6), 1.2 × 10(6), 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.
