The action of FeCl3 on N-acetyloxyamides leads to electron deficient species which can react intra or intermolecularly with an aromatic group to give oxindoles or analogues.
While β-nitrostyrene yields only hydroxymic or hydroxamic acid derivatives by treatment with acetyl chloride in the presence of zinc, tin, titanium or aluminium chloride, it also gives 3-chloro 2-indolinone and a 5-acetyl derivative of the latter, when the reaction is carried out with ferricchloride. The procedures of this reaction are examined, and a mechanism is suggested.
