Abstract
The photolysis of [Fe(Et(2)dtc)(3)],Et(2)dtc = diethyldithiocarbamate, in chloroform to yield [Fe(Et(2)dtc)(2)Cl] proceeds under 313 nm irra diation through a metal complex excited state, as expected. Under 254 nm irradiation, however, the dominant pathway is through a solvent-ini tiated reaction in which radicals formed after absorption of light by CHCl3 react thermally with [Fe(Et(2)dtc)(3)]. The initial rate varies linearly with the light intensity at 313 nm, but at 254 nm varies with the square root of the intensity.
