The role of pyridine (Py) in the bromination of p‐bromophenol (ArH) in CCl4 has been investigated. At constant concentrations of ArH and Br2, the rate of disappearance of Br2 increases to reach a limiting value as the concentration of Py is increased. The mechanism suggested to account for the rate expression, Rate = constant [ArH] [Br2]T[Py]T, obtained from the initial rate studies, involves the interaction between ArH and the brominating species Py. Br2, in the rate determining step. Py acts as a catalyst probably by virtue of its ability to polarise the Br‐Br bond. Copyright © 1971 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim
