Abstract:	Oxidation of propene on Bi₃Mo₂FeO₁₂ and Bi₂Mo₂Fe₂O₁₂ and Bi₂(MoO₄)₃ has been compared with the interaction of allyl iodide and diallyl oxalate with these compounds. Bi₂Mo₂Fe₂O₁₂ was found to be the most active and the least selective in propene oxidation. The three compounds show at the same time the same activity in acrolein formation from allyl iodide and oxalate. The results are interpreted in terms of the two-center mechanism of propene oxidation [9, 10]. The role of iron in elementary steps of propene oxidation on Bi–Mo–Fe–O catalysts is also discussed.
