| Abstract: | The reaction behavior of the title complexes have been investigated by means of in situ IR in nitrogen atmosphere. It has been found that they enabled the acetic acid to convert to acetone and methane in different temperatures. The results indicate that the sequence of the ketonization reaction activity for the clusters was V3OAT] > VFe2OAT], V2CrOAT] > Fe3OAT], VCr2OAT] > Cr3OAT] OAT = (mu 3-O) (mu-O2CCH3)6 (THF)3], and the sequence of the methanation reaction activity for the clusters was Cr3OAT] > VCr2OAT], V2CrOAT] > V3OAT] > VFe2OAT], Fe2OAH]. The ketonization reaction activity of Fe3OAT] were obviously lower than that of Fe3OAH] OAH = (mu 3-O) (mu-O2CCH3)6 (H2O)3] and the methanation reaction activity of Cr3OAT] were also much lower than that of Cr3OAH]. The difference between Fe3OAH], Cr3OAT] and Fe3OAH], Cr3OAH] mentioned above were discussed. |
