Reaction of Phenols with t-Butyl Bromide-Dimethyl Sulphoxide. Methylthiomethylation versus Bromination

t-Butyl bromide-activated dimethyl sulphoxide reacts with phenols to give either methylthiomethylation or bromination products.Several equilibria are shown to be simultaneously present in the system; however, by appropriate choice of several parameters (basicity, temperature, and reactant ratio) it is possible to drive the reaction selectively in one direction.A general discussion on the mechanism of these reactions is given.

2,4-Cyclohexadien-1-ones of formula types 1 to 5 (cf.Fig. 1) provide basic values and positional increments for UV and 13C NMR spectra.These parameters allow to distinguish between constitutional isomers belonging to one and the same column of the graph of Fig. 1.It has become possible, e.g., to identify clearly the constitutional isomers 6 and 8 or 12 and 14, respectively.
