It is noted that metal complexes of variable valency can act as efficient catalysts for many chemical redox-processes, including oxygen-alkaline cooking (delignification) of wood. It is shown that 1.10-phenanthrolinate copper (II) is the most active catalyst of delignification accelerating the process resulting from rate constant increase up to 15 – 28 times (depending on the process conditions and type of delignification material) at charge of ligand and central ion of 0,50 and 0,05% correspondingly of the dry wood mass.
