Efficient and environmentally friendly approach to the synthesis of ferrocenyl-substituted 1,5-diketone compounds under solvent-free conditions

This article describes a fast, efficient, economical, and environmentally friendly method for the preparation of a series of ferrocenyl-substituted 1,5-diketone compounds via Michael addition of ferrocenyl-substituted chalcones with deoxybenzoin or dibenzyl ketone under solvent-free conditions, and affords the corresponding Michael adducts with excellent yields of 77-93%.
