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 a

## Abstract A kinetic study of the first step in the reaction of phenol and formaldehyde, the formation of __ortho‐__ and __para__‐hydroxymethylphenol, is described. It is found that when using NaOH or KOH as a catalyst under weakly alkaline conditions (pH = 8.5‐10.5) at 30° C, the __para__‐positi
