In Situ IR Study of the Reaction Behavior of [Cr 3 (μ 3 -O)(μ-O 2 CH) 6 (H 2 O) 2 (O 2 CH)]· x H 2 O and its Active Fragments for the Addition Reaction of Acetylene
The reaction behavior of the complex [Cr3(μ3-O)(μ-O2CH)6-(H2O)2(O2CH)]·xH2O [shown as (Cr3FF)] has been investigated in the system of acetylene with water vapor by means of in situ 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.
