Aminophosphine Palladium

A new aminophosphine palladium(0) complex supported on ZrO.sub.2 nanoparticles (ZrO.sub.2@AEPH.sub.2-PPh.sub.2-Pd(0)) was successfully synthesized and characterized using FT-IR, XRD, XPS, SEM, TEM, EDS, TGA and ICP techniques. Characterization results revealed that the synthesized catalyst had tetragonal and monoclinic structure with spherical morphology. The prepared nanocatalyst was showed excellent reactivity in the Suzuki-Miyaura and Heck-Mizoroki cross-coupling reactions. Moreover, this nanocatalyst can be easily recovered and reused for at least six cycles without deterioration in catalytic activity.
