✦ Synopsis

An ultrafast time-resolved UV/visible absorption study of the UV photochemistry of [CpFe(CO)2] 2 (Cp = "qS-C5H 5) in cyclohexane solution has shown that the long-lived CO-loss product, CpzFe2(pL-CO)3, is produced within 40 ps. The immediate precursor has a lifetime of 15 ps and may be assigned preliminarily to the coordinatively unsaturated CO-loss product, (CpXCO)Fe(Ix-CO)zFe(Cp). The initial transient absorption decays with a lifetime of 1.6 ps, which defines the upper limit for the timescale of CO loss.
