Abstract:
A method for the side oxidation of the alkyl groups of compounds of the formula: ##STR28##whether R is selected from the group consisting of H, CH.sub.3, C.sub.2 H.sub.5, and i-C.sub.3 H.sub.7, R' is selected from the group consisting of H and CH.sub.3, and R"" is selected from the group consisting of H and CH.sub.3, wherein no more than two of the Group R, R' and R"" is H, said method being conducted in the presence of gaseous oxygen in the presence of the group consisting of palladium phenanthroline acetate catalyst and palladium acetate catalyst with a modified phenanthroline ligand of the formula: ##STR29##wherein R.sub.1 is selected from the group consisting of alkyl groups of from 1 to 3 carbon atoms, OH, and NO.sub.2 groups, and halogen and hydrogen atoms with at least six of the R.sub.1 groups being hydrogen atoms in the ligand.
