designed a series of hydroxy(aryl)‐λ3‐iodane–[18]crown‐6 complexes, prepared from the corresponding iodosylbenzene derivatives and superacids in the presence of [18]crown‐6, and have investigated their reactivities in aqueous media. These activated iodosylbenzene monomers are all non‐hygroscopic shelf‐storable reagents, but they maintain high oxidizing ability in water. The complexes are effective for
我们已经设计了一系列羟基(芳基)的-λ 3 -iodane- [18]冠-6配合物,从在存在相应的亚碘酰苯衍生物和超酸制备[18]冠-6,并在含水研究了它们的反应性媒体。这些活化的碘烷基苯单体都是非吸湿性的可货架存储的试剂,但是它们在水中具有很高的氧化能力。该络合物可在温和条件下有效氧化苯酚,硫化物,烯烃,甲硅烷基烯醇醚和烷基(三氟)硼酸酯。此外,羟基λ 3 -iodane- [18]冠-6配合物作为有效祖细胞为的二芳基- ,乙烯基-的合成,和炔基- λ 3水中的碘。在某些情况下,也可以使用其他极性较小的有机溶剂,例如甲醇,乙腈和二氯甲烷。
