Abstract
A semiempirical quantum chemical calculation was used to analyze the p ossible causes of the significant differences in the experimentally ob served catalytic and cocatalytic activity of carbamide in reactions of isocyanates. A substantial influence of complex formation of carbamid e with the basic reagent and the catalyst on the value of the cocataly tic activity of carbamide in the cyclotrimerization of isocyanates was demonstrated.
