Synthesis, Characterization of CoFe₂O₄ and CoAl_0.8Fe₂O₄: A Novel Catalyst for the Synthesis of 12-Aryl/Hetroaryl-8,9,10,12-Tetrahydrobenzo[a]Xanthen-11-Ones Derivatives in Semi-Aqueous Condition

Abstract

The current research focuses on the utilization of cobalt ferrite and Al-doped cobalt ferrite as catalysts for the synthesis of 12-aryl/heteroaryl-8,9,10,12-tetrahydrobenzo[a]xanthene-11-ones derivatives in semi-aqueous conditions. Doping some aluminum metal into CoFe₂O₄ improved its catalytic potential, which was then utilized in chemical synthesis. The produced catalyst was recycled in numerous reactions to test its stability. Characterization of the catalysts was done using FT-IR, XRD, BET, and SEM techniques. The grade of the catalysts was also determined by the yield of xanthene derivatives. The effect of pure cobalt ferrite and varied molar ratios of aluminum cobalt ferrite on the yield and reaction time of xanthene derivatives has been thoroughly explored. Xanthene derivatives having aryl moiety showed better results in terms of reaction times and yield as compared to heteroaryl. Cost-effective, recyclable catalysts producing excellent yield in short reaction time, with easy work method are some salient features of current research.
