Abstract
A series of N,N‐coordinate nickel (II) complexes with Schiff base ligands have been synthesized. All N,N‐coordinate nickel (II) complexes 1–4 were well characterized by IR and elemental analysis. Molecular structure of complex 1 was further characterized by single crystal X‐ray diffraction analysis. All air and moisture stable nickel complexes showed efficient catalytic activity for the amidation reaction of a widely range of amides and primary alcohols. N‐alkylated amides were given in good to excellent yields with liberating water as the sole byproduct. A variety types of functional groups tolerated well in such reaction condition. In addition, control experiments were carried out to understand this Ni‐catalysis protocol.
