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.
二铁九碳羰基和二甲胺的结合为甲基丙二酸二乙酯取代乙酸烯丙酯提供了一种活性催化剂。发现在一系列胺中,只有二甲胺和吗啉是该反应的有效促进剂。诸如二甲基甲酰胺(DMF)和N-甲基甲酰胺的溶剂要远远优于四氢呋喃,二氯甲烷和乙醇。
