A PROCESS FOR THE SELECTIVE CATALYTIC OXIDATION OF OLEFINS TO ALDEHYDES/KEYTONES WITH CLEAVAGE OF C=C BONDS

摘要

: A process for the selective catalytic oxidation of olefins to aldehydes/ketones with 5 cleavage of C=C bonds The use of compounds of the formula (I) R1aRebOc.Ld in which a = zero or an integer from 0 to 6 b = an integer from 1 to 4 c = an integer from 1 to 12 d = an integer from 0 to 4 L = Lewis base and the total of a, b and c is such as to comply with the penta- or hepta- valency of rhenium, with the proviso that c is not greater than 3.b, and in which R1 is absent, identical or different and is an aliphatic hydrocarbon radical having 1 to 10 carbon atoms, an aromatic hydrocarbon radical having 6 to 10 carbon atoms or an arylalkyl radical having 7 to 9 carbon atoms, where the R1 radicals can, where appropriate, be substituted identically or differently, independently of one another, as catalysts for the selective oxidation of olefins with cleavage of C=C bonds to give the corresponding carbonyl compounds in the presence of a peroxide-containing compound, where the amount of substance ratio of olefin to peroxide-containing compound is in a range from 1 : 2 to 1 : 14.
