The acrolein is generally produced through the catalytic oxidation of propylene.
The catalytic ability of Lewis acids, such as hydrogen, halogen, chalcogen, and pnictogen bonded species, is traditionally attributed to the lowering of the LUMO of the activated dienophile, resulting in a smaller, i. e., more favorable, HOMO diene-LUMO dienophile energy gap and hence stronger orbital interaction. 14 Recently, however, we have shown that this rationale is incomplete.
