Oxidation and dehydrogenation of a phenol ether in a pentasil zeolite (Na ZSM-5): an EPR study
Abstract
Incorporation of p-propylanisole 1 onto a pentasil zeolite (Na ZSM-5) gives rise to the EPR spectrum of anethole radical cation 2˙+; this conversion requires three separate oxidation steps alternating with two deprotonations, a reaction sequence of remarkable complexity for a room temperature reaction, albeit on the internal surfaces of a zeolite.
