Abstract
The invention relates to a method for the high yield production of dicarboxylic acids such as azelaic acid by the controlled two step oxidation of an unsaturated hydrocarbon substrate. The method consists of two steps and involves the derivatization of the unsaturated substrate which locks and directs oxidative cleavage at the site of unsaturation to yield the desired acids.
