Abstract
Methyl ketones are prepared in liquid phase by oxidizing terminal olefins of the formula R--CH.dbd.Ch.sub.2, where R is a hydrocarbon radical. The oxidizing agent is hydrogen peroxide or an organic hydroperoxide, and the catalyst is a palladium catalyst of the formula Pd AA' where A is fluoborate, acetate or trifluoroacetate, and A' is OOR.sub.1 and where R.sub.1 is a hydrocarbon radical.
Claims19
A process for producing a methyl ketone of the formula ##STR2## from an olefin of the formula RCH.dbd.CH.sub.2, wherein R is C.sub.1-20 hydrocarbyl, said process comprising the step consisting essentially of contacting said olefin in the liquid phase with a palladium catalyst and a peroxide oxidizing agent:
- wherein said palladium catalyst has the formula PdAA', wherein A is fluoborate, acetate or trifluoroacetate;
- and A' is OOR.sub.1, wherein R.sub.1 is C.sub.3-20 hydrocarbyl;
- and
- wherein said oxidizing agent is hydrogen peroxide or an organic hydroperoxide of the formula R.sub.2 OOH, wherein R.sub.2 is C.sub.4-20 tertiary alkyl, aralkyl or alkylaryl.
