Palladium-3,4-dihydroxybenzaldehyde complex supported on MCM-41 was synthesized by a post-grafting method as selective complex a and shows remarkable properties such as thermal and chemical stability, reusable, easily prepared from very cheap materials and can be used as an efficient and versatile catalyst for Mizoroki–Heck and Suzuki–Miyaura cross-coupling reaction. This catalyst was characterized by SEM, TEM, EDX, XRD, FT-IR, TGA, BET and ICP techniques. The synthesized Pd-BS-MCM-41 heterogeneous catalyst could be recovered easily and reused several times without significant loss of its catalytic activity. Further investigations showed that among different aryl halides that used for the synthesis of biaryls and butyl cinnamate derivatives, the reactivity of aryl iodides is higher than aryl bromides, and aryl chlorides. The heterogeneity manner of this nanocatalyst was confirmed via a hot filtration test.
