Reactions of lead tetra-acetate. Part VIII. The reactions of azoacetates with base

Azoacetates, derived from aromatic ketone arylhydrazones with lead tetra-acetate, react with base to give one or more of three products, namely, an indazole, the parent ketone, and the parent arylhydrazone. Variations in the course of the reactions with the structure of the azoacetate are discussed.
