Abstract

Employing fast time-resolved infrared (TRIR) spectroscopy we have characterized CpRe(CO)₂(n-heptane), CpRe(CO)₂(Xe), and CpRe(CO)₂(Kr) (Cp = η⁵-C₅H₅) at or above room temperature in n-heptane, supercritical Xe, and Kr solution. The reactivity of CpRe(CO)₂(n-heptane) with CO (k₂ = 2.1 (±0.5) x 10³ mol^-1 dm³ s^-1) shows this complex to be the least reactive of the reported organometallic alkane complexes. We report a trend in reactivity of the early transition metal alkane complexes. CpRe(CO)₂(Xe) and CpRe(CO)₂(Kr) are also shown to have significant stability. CpRe(CO)₂(Xe) is less reactive toward CO than all of the reported alkane complexes except CpRe(CO)₂(n-heptane).
