Description
Summary:Herein a novel cobalt complex prepared by combination of Co(NO3)2.6H2O and thiosalycilic acid. Prepared microsphere cobalt complex was characterized by XRD, FTIR, TGA, BET, ICP and SEM techniques. Also, we report here an efficient method for the preparation of pyrroloacridine‐1(2H)‐one derivatives from a three‐component condensation reaction of amine, dimedone, and isatin and synthesis of chromeno [2, 3‐ d] pyrimidin‐8‐amines by reaction of benzaldehyde, α‐naphthol, malononitrile, and ammonium acetate in the presence of microsphere cobalt complex as the catalyst. The microsphere cobalt complex can be recovered without great loss of catalytic activity. A new microsphere cobalt complex prepared via reaction of Co(NO3)2.6H2O and thiosalycilic acid using the solvothermal method. The structure of synthesized catalyst was confirmed by XRD, FTIR, TGA, BET, ICP and SEM techniques. This catalyst shown a high catalytic activity in synthesis of pyrroloacridine‐1(2H)‐one and chromeno [2, 3‐ d] pyrimidin‐8‐amines.
