The Buchwald–Hartwig reaction for arylation of amines and amides was achieved by magnetic Nanocat-Fe–Pd in moderate to excellent yields.

A nano-sized Magnesia–Zirconia (nano-MgO–ZrO₂) catalyst was prepared by a simple ultradilution co-precipitation method and by using inexpensive precursors. The nano-MgO–ZrO₂ was extensively characterized by SIMS together with other analytical techniques such as X-ray diffraction (XRD) and transmission electron microscopy (TEM). The nano-MgO–ZrO₂ catalyst proved to be very efficient for the reduction of carbonyl compounds and multicomponent reactions under mild reaction conditions. The recyclability and reusability of the nano-MgO–ZrO₂ catalyst has been tested.
