Experimental results suggested that the oxidation and ammoxidation of propylene and allyl iodide on molybdenum trioxide and bismuth molybdates involved concerted chemisorption, ..cap alpha..-hydrogen abstraction, and subsequent oxygen or NH insertion to form acrolein in the absence and acrylonitrile in the presence of ammonia. Some allyl radicals, which apparently formed, were not the selective intermediates in the catalytic propylene oxidation. The detailed mechanisms were derived from product distributions obtained in the pulsed reactions of allyl iodide, propylene, and allyl radicals obtained by in-situ decomposition of 3,3'-azopropene on molybdenum trioxide, bismuth trioxide, and bismuth molybate containing 1:1, 1:2, and 1:3 Bi/sub 2/O/sub 3/ to MoO/sub 3/ at 320/sup 0/C.
