  text: <jats:title>Abstract</jats:title><jats:p>The decomposition and reduction of
    ferrocene, an important precursor for iron chemical vapor deposition and catalyst
    for nanotube synthesis, is investigated in the gas‐phase. Reactive intermediates
    are detected to understand the underlying chemistry by using a microreactor coupled
    to a synchrotron light source. Utilizing soft photoionization coupled with photoelectron‐photoion
    coincidence detection enables us to characterize exclusive intermediates isomer‐selectively.
    A reaction mechanism for the ferrocene decomposition is proposed, which proceeds
    as a two‐step process. Initially, the molecule decomposes in a homogeneous surface
    reaction at temperatures &lt;900 K, leading to products such as cyclopentadiene
    and cyclopentadienyl radicals that are immediately released to the gas‐phase.
    At higher temperatures, ferrocene rapidly decomposes in the gas‐phase, losing
    two cyclopentadienyl radicals in conjunction with iron. The addition of hydrogen
    to the reaction mixture reduces the decomposition temperature, and changes the
    branching ratio of the products. This change is mainly attributed to the H‐addition
    of cyclopentadienyl radicals on the surface, which leads to a release of cyclopentadiene
    into the gas‐phase. On the surface, ligand fragments may also undergo a series
    of catalytic H‐losses leading most probably to a high carbon content in the film.
    Finally, Arrhenius parameters for both global reactions are presented.</jats:p>
