ABSTRACT:
Improved catalysts for the reduction of oxyhalide depolarizers such as SOCl.sub.2 and SO.sub.2 Cl.sub.2 in active-metal non-aqueous cells are provided which are easier to prepare and less expensive than phthalocyanine complexes and which are generally more stable in the cell environment. These catalysts include certain macrocyclic complexes of Schiff's base prepared by the reaction of an aldehyde with a primary diamine. The preferred embodiments include mononuclear metal macrocyclic complexes made from salicylaldehyde and o-phenylenediamine and binuclear metal macrocyclic complexes of 5-methyl isophthalaldehyde and 1,3-diaminopropane.
