In this work, 4-AMTT-Pd complex over Fe3O4@SiO2 as supported catalysts for C-C cross-coupling reactions have been applied. In the first part, Fe 3 O 4 @SiO 2 -4-AMTT -Pd used in Sonogashira cross coupling reaction. The conversions under optimized conditions, using K 2 CO 3 as base, room temperature and Solvent-Free Condition s were excellent. In the next parts, This catalyst used in Suzuki and Heck cross coupling reactions, good activities were observed. The desired products were obtained in good yields at 50 0 C within short reaction times under optimized conditions. The intended catalyst was characterized by the FT-IR, FE-SEM, TEM, VSM, TGA and XRD techniques. Also the techniques 1 H-NMR, FT-IR and GC were used for characterization of products.
