Reactions of methoxy hydroperoxides derived from methyl oleate. Catalytic hydrogenation

Yield improvements in carbonyl compounds obtained by catalytic hydrogenation of methyl oleate ozonolysis products have been achieved by use of catalyst poisons and by the proper choice of catalyst support. Byproduct dimethyl azelate formation with palladium on charcoal was about 20% in the absence of a poison; 10%, with sodium acetate present in the support; 8%, with triethyl amine in solution. Palladium on calcium carbonate‐lead acetate gave about 7%, palladium on zine oxide with pyridine or lead acetate present gave 9%. The literature is reviewed on the catalytic hydrogenation of methoxy hydroperoxides derived from ozonolyses in methanol.
