✦ Synopsis

Bifunctional catalysis has been observed in a variety of reactions and the possible role of such catalysis in enzyme systems has been discussed.1 Amides other than 2-pyridone, have not been shown to be effective bifunctional catalysts.

2 We now report evidence for bifunctional catalysis by amides and ureas in the reaction between amines and phenylisocyanate.

Catalysis by products is a general feature of the reactions of isocyanates.
