Oxidative Amidation of Ferrocenyl Aldehydes with Amines Catalyzed by Chalcogenised FeSe(CO) Cluster: Direct Transformation of Aldehyde to Amides.

With the interest and knowing the importance of ferrocenyl conjugates, a direct amidation of ferrocenyl aldehyde has been developed under feasible conditions. Varieties of amines has been oxidatively coupled with ferrocene aldehyde in the presence of highly economical and robustly stable iron chalcogenide ironcarbonyl clusters [FeE(CO), E= S, Se, and Te] and TBHP. The reaction worked in greener solvent water at a moderate temperature of 70 °C and the ferrocenyl-amides in just 30 minutes.
