Abstract

The synergetic action of two nickel(II) ions embedded in a tunable dinucleating ligand matrix (illustrated) allows manifold cooperative reactions within the bimetallic pocket, such as the hydration of nitriles, the hydrolysis of esters, and the degradation of urea to cyanate. Related mononuclear complexes have been prepared in order to further elucidate mechanistic aspects of these transformations.
