A metal sequestering material can be contacted with a reaction mixture of a metal-catalyzed reaction to remove transition metals or transition metal complexes. The reaction mixture contains transition metals and a reaction product in solution. These transition metals may be, for example, Pd, Ir, Ru, Rh, Pt, Au, or Hg. The concentration of transition metals in the reaction mixture is reduced to less than 100 ppm or even less than 10 ppm. |
