Abstract: Disclosed are nickel-containing complexation precursors having high complexation activity for bidentate processed under various conditions phosphite ligands. Also disclosed are methods of making the complexation precursors. The disclosed method of generating the nickel-containing complexation precursor includes including contacting a nickel starting material with a reductant under conditions sufficient to generate a nickel-containing complexation precursor having at least about 1,500 ppmw sulfur in the form of sulfide.
