A novel green tea extract-encapsulated silica gel decorated with in situ-generated Pd nanoparticles is reported as an efficient, green heterogeneous catalyst in the Buchwald-Hartwig C-N cross-coupling reaction. It was characterized by several anal. techniques. Thereafter, a wide range of aryl amines were synthesized in good to excellent yields by reaction of different substituted aryl halides and secondary amines over the catalyst. The material is sufficiently stable and could be used at least six times in a model Buchwald-Hartwig reaction without noticeable change in its catalytic activity. Heterogeneity of the catalyst was examined by a hot filtration test. The results came from multiple reactions, including the reaction of 1-Iodo-4-methylbenzene(cas: 624-31-7Application of 624-31-7)
