3-Hydroxypyrroles and 1H-Pyrrol-3(H)-ones. Part 9. Diazo-coupling Reactions of 1-Substituted-1H-pyrrol-3(2H)-ones

Reaction of 1-substituted 1H-pyrrol-3(2H)-ones 6 and 7 with diazonium salts under acidic conditions gives rise to 2-coupled products, which are shown by X-ray crystallography to adopt the ketohydrazone structures 9-11 K.
