HCID 23925IronCatalyst

Procedure

Two representative iron catalysts were obtained as follows: 2,4-dimethyl-1,3-pentadienide iron pentane solution was added to dry silica in a 50 ml flask. The mixture was stirred for 3 hours at room temperature. The pentane solvent was evaporated and the greenish solid was obtained. Catalyst A, “Reduced” Fe/SiO2, as shown in Table 2, was obtained when the 2,4-dimethyl-1,3-pentadienide iron on silica catalyst was treated with H2 without being exposed to air at temperatures from 350-500° C. Catalyst B, the “Oxidized” Fe/SiO2, as shown in Table 2, was obtained when the 2,4-dimethyl-1,3-pentadienide iron on silica was exposed to air at room temperature directly after it's synthesized.
