Low-amount palladium supported on Fe-Cu MOF: Synergetic effect between Pd, Cu and Fe in Sonogashira-Hagihara coupling reaction and reduction of organic dyes

FeCu MOF has been prepared via solvothermal method and the resulting bimetallic MOF was employed for stabilization of Pd species. Obtained Pd(II)@NH2BDC-FeCu MOF could act as an effective environmental catalyst in Sonogashira-Hagihara coupling reaction and the reduction of organic dyes. This recyclable catalyst demonstrated high catalytic activity for Sonogashira reaction of aryl iodides and aryl bromides with alkynes. Rhodamine B and methyl red as organic dyes were instantly reduced. Pd(II)@NH2BDC-FeCu/MOF was characterized by TEM, XPS, FT-IR, BET, XRD, and SEM. In addition, the synthesized catalyst was recyclable and reusable for 6 sequential times without deteriorating remarkable in catalytic performance for reaction of iodobenzene with phenylacetylene.
