Abstract In this study the “phase-vanishing” method for diffusion-controlled addition of a reagent (Br 2) to a reaction phase via a fluorous membrane (C 8 F 18) is combined with an additional mode of activation (visible-light) to achieve the benzyl bromination of various alkyl- substituted aromatic compounds in a concentrated solution. Benzyl bromination of p-tert- butyltoluene proceeded in various solvents including hexane and methanol, while the ...
