Abstract
Abstract The anodic oxidation of 2,6-di-t-butyl-4-methylphenolate (IId), as well as the 4-ethyl (IIc) and 4-n-butyl (IIe) derivatives, has been studied by cyclic voltammetry in acetonitrile with a platinum disk electrode. The initially formed phenoxyl radicals (III) dimerize reversibly to form the para-quinol ethers and the reaction has been characterized quantitatively by cyclic voltammetry. The values of kf1/2K−3/4 are 0.20, 0.23 and 0.6 s−1/2 (mol/l)1/4 for IIIc-e respectively where kf is the dimerization rate constant and K is the dimarization equilibrium constant. Values of K have been estimated from peak potential measurements.
