利用原位红外光谱研究标题化合物在N2 中的反应行为。发现它们在不同温度下能使乙酸分别转化为丙酮和甲烷。它们对乙酸的丙酮化反应活性顺序 :[V3OAT]>[VFe2 OAT],[V2 CrOAT]>[Fe3OAT],[VCr2 OAT]>[Cr3OAT][OAT =(μ3 O) (μ O2 CCH3) 6(THF) 3]。它们对乙酸的甲烷化反应活性顺序 :[Cr3OAT]>[VCr2 OAT],[V2 CrOAT]>[V3OAT]>[VFe2 OAT],[FeO3OAT]。对乙酸的丙酮化反应活性[Fe3OAT]明显低于 [Fe3OAH][OAH =(μ3 O) (μ O2 CCH3) 6(H2 O) 3]。对乙酸的甲烷化反应活性 [Cr3OAT]也明显低于 [CrOAH]。并对上述 [Fe3OAT],[Cr3OAT]与 [Fe3OAH],[Cr3OAH]之间差异进行了讨论。
In situ FTIR spectroscopy was used to study the reaction behavior of the title compound in N2. They were found to convert acetic acid to acetone and methane, respectively, at different temperatures. Their acetonic reactivity toward acetic acid is as follows: [V3OAT]> [VFe2 OAT], [V2 CrOAT]> [Fe3 OAT], [VCr2 OAT]> [Cr3 OAT] [OAT = (μ3 O) (μ O2 CCH3) THF) 3]. Their methanation reactivity to acetic acid is in the order of [Cr3OAT]> [VCr2 OAT], [V2 CrOAT]> [V3OAT]> [VFe2 OAT], [FeO3 OAT]. Acetone reaction activity [Fe3OAT] for acetic acid was significantly lower than [Fe3OAH] [OAH = (μ3 O) (μ O2 CCH3) 6 (H2 O) 3]. Methanation reactivity to acetic acid [Cr3OAT] was also significantly lower than [CrOAH]. The differences between [Fe3OAT], [Cr3OAT] and [Fe3OAH] and [Cr3OAH] described above are also discussed.
