    Abstract: A method of depolymerizing a lignin includes oxidizing the lignin to provide an oxidized lignin wherein benzylic —OH of ?-O-4 linkages have been converted to carbonyl. The oxidized lignin is depolymerized with a metal selected from the group consisting of zinc, magnesium, aluminum and titanium or mixtures thereof, in the presence of an ammonium salt or carbon dioxide. Also described are methods for manufacturing phenolic products from lignin and a method for the cleavage of a ?-O-4 linkage in a substrate.
