Abstract
Flash photolysis has proven to be an effective technique for determining reaction mechanisms. Upon photolysis, a CO ligand is removed from Cr(CO)6 forming the reactive molecular fragment Cr(C0)5. In the presence of alkene, L, Cr(CO)s can react to form the meta-stable intermediate Cr(C0)5L. At high L concentrations, Cr(CO)5L decays by pseudo-first-order kinetics with an observed rate constant, kobs, which is dependent on the concentration of both L and added CO. The exar.t nature of the dependence provides insight into the mechanism of the decay of Cr(C0)5L and a plot of 1/kobs vs. [L] will give the rate constants for both the dissociation and formation of this complex.
