A stable and powerful heterogeneous palladium catalyst was synthesized using immobilized palladium on ( S )‐methyl histidinate bonded onto the surface of multi‐walled carbon nanotubes . The catalyst was characterized using a combination of Fourier transform infrared and X‐ray photoelectron spectroscopies, transmission electron microscopy , X‐ray powder diffraction and inductively coupled plasma , thermogravimetric and elemental analyses. This new air‐ and moisture‐stable phosphine‐free palladium catalyst was found to be highly active and reusable in Mizoroki–Heck and Suzuki–Miyaura cross‐coupling reactions in poly(ethylene glycol) and aqueous ethanol as green solvents using an extremely small amount of palladium under mild conditions.
