Abstract:
A process for the selective catalytic oxidation of olefins to the corresponding carbonyl compound which comprises oxidizing olefins and a peroxide-containing compound in a liquid medium in the presence of a catalyst, wherein the catalyst is of the formulaeR.sup.1.sub.a Re.sub.b O.sub.c.cndot.L.sub.d (I),in whicha=zero or an integer from 0 to 6b=an integer from 1 to 4c=an integer from 1 to 12d=an integer from 0 to 4L=Lewis baseand the total of a, b and c is such as to comply with the penta- or heptavalency of rhenium, with the proviso that c is not greater than 3.cndot.b, andin whichR.sup.1 is absent or 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 R.sup.1 radicals where appropriate is optionally substituted identically or differently, independently of one another, the ratio of olefinic double bonds to peroxide-containing compound is in a range form 1:2 to 1:14.
