ABSTRACT:
Olefins oxidized with organic hydroperoxides in the presence of water and the appropriate metal catalyst at temperatures in the range of 140.degree. to 250.degree. C. give high yields of the corresponding ketone (based on the hydroperoxide charged.) For example, 2-methyl-2-butene reacted at 155.degree. C. at autogenous pressure in the presence of H.sub.2 O and molybdenum ions with 1.008 moles of t-butylhydroperoxide gave 0.90 mole of 2-methyl-3-butanone, a 90% yield.
