Abstract
The method of oxidizing the alkyl groups of alkylbenzenes using palladium phenanthroline acetate or a palladium acetate with modified phenanthroline ligand catalyst. The palladium acetate catalyst with modified phenanthroline has the following formula: wherein R1 is selected from the group consisting of alkyl groups of from 1 to 3 carbon atoms, OH, and NO2 groups and halogen and hydrogen atoms with at least six of the R1 groups being hydrogen atoms in the ligand.
Claims7
A method for the side oxidation of the alkyl groups of compounds of the formula:
- whether R is selected from the group consisting of H, CH3, C2H5, and i-C3H7, R′ is selected from the group consisting of H and CH3, and R″ is selected from the group consisting of H and CH3, 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:
- wherein R1 is selected from the group consisting of alkyl groups of from 1 to 3 carbon atoms, OH, and NO2 groups, and halogen and hydrogen atoms with at least six of the R1 groups being hydrogen atoms in the ligand.
