The coupling of diazonium salts from isatic acids with alkoxycarbonylmethylenephosphoranes leads directly to 3-oxo-indazolin-2-yl-(alkoxycarbonyl) methylenetriphenylphosphoranes, while coupling with methyl 2-chloroacetacetate gives 2-[2-(methoxycarbonyl-chloromethyliden)hydrazino] -phenyl-glyoxylic acid. © 1986.

Abstract
The coupling of diazonium salts from isatic acids with alkoxycarbonylmethylenephosphoranes leads directly to 3-oxo-indazolin-2-yl-(alkoxycarbonyl) methylenetriphenylphosphoranes, while coupling with methyl 2-chloroacetacetate gives 2-[2-(methoxycarbonyl-chloromethyliden)hydrazino] -phenyl-glyoxylic acid. © 1986.
