Formyl methyl was generated by photodissociation of methyl vinyl ether, at 298
Here the vinoxy radical
undergoes rapid electron rearrangement to the lower energy form (ca. 16 kcal/mol lower)
formyl methyl structure. Kinetic studies on this formyl methyl radical with 02 show a
, relative to those reportedly for acetyl radical,
This suggests that formyl methyl radicals produced in
experiments on C1 or OH reaction with acetaldehyde will react about one tenth as fast
with 02, probably requiring a small or no correction to kinetic data of the faster acetyl +
02 reactions. It also suggests that a barrier to the association may exist or that there is a
very low well depth for the formyl methyl + 02 adduct.
