Abstract A new and efficient method has been developed for the conversion of α,β-unsaturated ketones to 1,5-diketones via tandem retro-Aldol and Michael addition in the presence of Co(acac)2 covalently anchored amine functionalized silica [AS-Co(acac)2]. The single crystal X-ray crystallography confirms the formation of 1,5-diketones. This method has been proved to be an attractive alternative to existing methodologies under conventional homogeneous catalysis with the frequent troublesome manipulation and work-up. The AS-Co(acac)2 was found to be highly active and could be recycled for four consecutive runs with slight decrease in activity.
