Abstract

Near-UV irradiation of (η⁴-C₄H₄)Fe(CO)₃, at low temperature In alkane containing Et₃SiH or In neat Et₃SiH yields CO loss to give the IR detectable 16-electron (η⁴-C₄H₄)Fe(CO)₂ which subsequently reacts thermally with the excess Et₃SiH to give (η⁴-C₄H₄)Fe(H)(SiEt₃)(CO)₂. The rate of reaction is strictly first order in (η⁴-C₄H₄)Fe-(CO)₂ and depends on temperature; the Arrhenius activation energy is 46 ± 4 kJ/mol from rate measurements in the range 100–160 K.
