摘要

苯并碘氧硼烷三甲酸甲酯是一种独特的苄烯前体，可在室温下于 NaHCO 3 存在的水溶液条件下生成。在这些条件下，烷基芳基硫化物与生成的苄炔发生反应，可选择性地得到相应的锍盐。与此相反，之前报道的烷基芳基硫化物与普通苄炔前体在强碱性无水条件下发生的反应会产生各种环化、重排产物。

Generation of Benzyne from Aryl Benziodoxaborole Triflate under Aqueous Conditions and its Reactions with Alkyl Aryl Sulfides

Mesityl benziodoxaborole triflate is a unique benzyne precursor under aqueous conditions in the presence of NaHCO 3 at room temperature. Reactions of alkyl aryl sulfides with benzyne generated under these conditions selectively afford the corresponding sulfonium salts. In contrast, the previously reported reactions of alkyl aryl sulfides with common benzyne precursors under strongly basic anhydrous conditions lead to various products of cyclization, rearrangement
