F. Loeker et W. Leitner, Steel-promoted oxidation of olefins in supercritical carbon dioxide using dioxygen in the presence of aldehydes, CHEM-EUR J, 6(11), 2000, pp. 2011-2015
Oxidation of olefins occurs effectively in supercritical carbon dioxide as
the reaction medium with dioxygen as the primary oxidant and aldehydes as s
acrificial co-oxidants. No catalyst is required, but the: reaction is promo
ted by the stainless steel of the reactor walls. Depending on the substrate
, vinylic oxidation or epoxidation can be the prevailing pathway. Epoxidati
on is particularly effective for substrates with internal double bonds and
for long-chain terminal olefins.
