- Orthoamide, LX [1]. N,N,N',N'-Tetraformylhydrazine- a Formylation Agent for Aromatic Compounds of Wide Scope
-
The reagent system formed from N,N,N',N'-tetraformylhydrazine (3) and aluminum chloride allows the formylation of aromatic compounds. The scope of the method is comparable with the Olah formylation and the Gross-Rieche procedure, since benzene and fluorobenzene can be formylated. Two formyl groups are transferred from 3 to the aromatic nuclei when a molar ratio 4:1:4 (aluminum chloride/3/aromatic compound) is chosen.
