Background: Metal oxide or metal oxide composite nanoparticles are attaining tremendous importance due to their catalytic activities for various organic transformations.
Objective: We have reported firstly, one pot synthesis of xanthene derivatives prepared by ZnS-Fe2O3-Ag composite under solvent free conditions. ZnS-Fe2O3-Ag composite
Method: This nanocomposite prepared by facile and simple hydrothermal approach.
Results: The prepared composite is smaller (17.56 nm) in size and can be easily separable, recycled and reused for six times without any significant loss of catalytic activity with excellent yields. In short reaction time, great catalytic activity was perceived with no co-catalyst and any other activator.
Conclusion: In conclusion, ZnS-Fe2O3-Ag composite provide an simple, economic, efficient and greener method for the synthesis of one pot multi component reaction of aldehyde with 1,3-diketones under solvent free conditions for the synthesis of 1,8-dioxooctahydro xanthenes. In short reaction time, great catalytic activity was perceived with no co-catalyst and any other activator.
