Kinetics and mechanism of reactions between 2,4,6-trinitrofluorobenzene and alcohols

Abstract

The kinetics of formation of some ethers from alcohols and 2,4,6-trinitrofluorobenzene were studied under first order conditions ([ROH]_o > [TNFB]_o). In CCl₄, k (in dm³ s^–1 mol^–1) values are increased on increasing the values of the initial concentrations of the alcohols. This anomalous kinetic behaviour parallels that of reactions between amines and activated aromatic fluoro derivatives. The presence of a substrate–alcohol interaction which precedes the substitution process explains the kinetic behaviour of the alcohols.
