An efficient generation method and remarkable reactivities of 3-triflyloxybenzyne
3-Triflyloxybenzyne was generated via an iodine–magnesium exchange reaction of 1, 3-bis
(triflyloxy)-2-iodobenzene using the trimethylsilylmethyl Grignard reagent. Various
arynophiles and nucleophiles reacted regioselectively with 3-triflyoxybenzyne to afford
cycloadducts and unique aryl triflones, which were provided via thia-Fries rearrangement.

3-Triflyloxybenzyne was generated via an iodine–magnesium exchange reaction of 1,3-bis(triflyloxy)-2-iodobenzene using the trimethylsilylmethyl Grignard reagent. Various arynophiles and nucleophiles reacted regioselectively with 3-triflyoxybenzyne to afford cycloadducts and unique aryl triflones, which were provided via thia-Fries rearrangement.
