Abstrakt: The present study is focused on the synthesis of DHPMs by using NiCoSe2 and NiCo2S4 as heterogeneous catalysts, and they are characterized by using XRD, SEM, TEM, BET and XPS. The NiCoSe2 and NiCo2S4 catalysts proved to be the most suitable catalytic system when compared to conventionally reported catalysts in terms of yield and reaction time. NiCoSe2 and NiCo2S4 are environment-friendly catalysts and can be recycled over 5 cycles with a negligible loss in the catalytic performance. Thus, the synthesized catalysts were successfully utilized in the synthesis of biologically active DHPMs, and all compounds were characterized using mass and NMR spectroscopic techniques.
