Pd on surface-modified NiFe2O4 nanoparticles: a magnetically recoverable catalyst for Suzuki and Heck reactions.

This communication reports on the use of NiFe2O4-DA-Pd, a complete magnetically separable catalyst for Suzuki and Heck coupling reactions of aromatic halide derivatives. The catalyst efficiency for the coupling of chloro derivatives is as good as bromo and iodo derivatives. Catalytic efficiency remains unaltered even after three repeated cycles.
