A new base‐metal bifunctional catalyst NH‐Pd(0)@MNP was prepared via a facile procedure and fully characterized. The as‐prepared catalyst was used as an efficient relay catalyst for the one‐pot oxidant‐free dehydrogenation‐Knoevenagel condensation tandem reaction from benzyl alcohol in H 2 O under mild conditions and generated benzalmalononitriles with yield up to 96%. Meanwhile, the catalyst could be easily recovered from the reaction system by an external magnetic field, and is reusable with little loss of activity up to 6 runs (<5%).
