While the 4-Me-substituted derivate 2b could be obtained with a yield of 88%, OMe substitution resulted in a decomposition of 2c as already observed for the O-bridged diaryliodonium triflate 1f. For desactivated substrates it was again necessary to apply further amounts of oxidant after an initial oxidation time. Under these modified conditions, Br-and F-substituted derivates 2d and 2e were obtained in up to 86% yield.
