Polyurethane formation from 4,4′-diphenylmethane diisocyanate [101-68-8] and diethylene glycol (I) [111-46-6] in the presence of Cu β-diketone complex catalysts proceeds via a coordination mechanism and depends to a significant degree on substituents on the ligands. The catalytic effect is associated with complexation with I. Activation of side reactions is not observed in the presence of the β-diketone complexes. The polyurethanes formed using these catalysts are more heat resistant than those formed in their absence. The catalytic activity of the Cu β-diketones is related to their Taft substituent constants
