The Facile Syntheses of Aldehydes and Aldehydic Acids from Carboxylic Acid Anhydrides Using Disodium Tetracarbonylferrate (–II)

Abstract

Abstract Disodium tetracarbonylferrate reacts readily with aliphatic and aromatic carboxylic acid anhydrides under mild conditions; the corresponding aldehydes are formed in high yields by quenching the reaction solution with acetic acid. Intermolecular anhydrides give aldehydes and acids, and intramolecular ones give aldehydic acids. The reaction mechanism via acylcarbonylferrates is assumed.
