1-Acetyl- and 1-benzoyl-2- and -3-phenyliminooxoindolines were synthesized. o-(Acetylamino)phenylglyoxylic acid anil was prepared from 1-acetyl-3-phenylimino-2-oxoindoline. More stable o-(acetylamino)phenylglyoxylanilide anil can be prepared not only from o-(acetylamino)phenylglyoxylanilide but also from an ester or chloride of o-(acetylamino)phenylglyoxylic acid anil. o-(Acetylamino)phenylglyoxylothiosemicarbazide was prepared from o-(acetylamino)phenylglyoxylic acid anil and from the corresponding anilide.

A series of 2-hydroxy-3-arylazo-1,4-naphthoquinones were prepared by coupling of 2-hydroxy1,4-naphthoquinone with aryldiazonium chlorides. The reactivity of the products toward electrophilic and nucleophilic agents was studied. In reaction with o-phenylenediamine they give condensation products, the corresponding benzo[a]phenazines.
