Moreover, effects different Lewis acid, basic, ionic liquid catalysts, as well solvent catalyst dose on investigated. Both catalysts demonstrated strong capability in carefully regulated ideal circumstances. Heterogeneous exhibited superior performance compared homogeneous BTP‐Fe. All products obtained high TOF (turnover frequency) numbers presence these which indicate efficiency synthesis dihydro‐7H‐5‐thia‐hexaaza‐s‐indacen‐6‐one derivatives. two catalysts' recycling reusability reactions also could be reused up seven times efficiency, but (BTP‐Fe) only recycled four times. Furthermore, mechanism was suggested supported DFT calculation. simplicity, safety, stability, use commercially available quick times, excellent yields make it promising future industrial use.
