Abstract

The reaction behavior of the complex [Cr₃(μ₃-O)(μ-O₂CH)₆-(H₂O)₂(O₂CH)]·<i>x</i>H₂O [shown as (Cr₃FF)] has been investigated in the system of acetylene with water vapor by means of <i>in situ</i> IR and TG analyses. It has been observed that some active fragments obtained by the loss of part of the ligands of (Cr₃FF) demonstrated activity for the additional reaction of acetylene with water or hydrogen, forming either acetaldehyde or ethylene. On the basis of the study of the thermo-decomposition process, as well as the FAB-MS data, the nature of these active fragments has been elucidated.
