Iron‐Catalyzed Nucleophilic Substitution of Allylic Acetate

Abstract

Abstract The combination of diiron nonacarbonyl and dimethylamine gives an active catalyst for displacement of allylic acetate by diethyl methylmalonate. It was found that among a series of amines, only dimethylamine and morpholine were efficient promoters of the reaction. Solvents such as dimethylformamide (DMF) and N ‐methylformamide were much superior to tetrahydrofuran, dichloromethane, and ethanol.
