A new class of catalyst for the preparation of rigid polyurethane (RPUR) foams was developed. Metal(II)amine complexes [M(en) 2 and M(trien), where M ¼ Cu or Ni, en ¼ ethylenediamine, and trien ¼ triethylenetetramine] were synthesized and used as catalysts in the preparation of RPUR foams. The catal
