cause functional group incompatibility, especially when polyfunctionalized derivatives are desired. This work describes the direct synthesis of monoaryl‐λ3‐iodanes through a chemoselective ipso‐substitution reaction of arylgermanes and arylstannanes with iodine tris(trifluoroacetate). The generated iodanes were converted to iodonium ylides or used for further transformations in one pot. The presented
单芳基-λ 3 -iodanes是潜在有吸引力的芳基化剂。它们通常是通过氧化从芳基碘化物合成的,这会引起官能团的不相容性,尤其是在需要多官能化衍生物的情况下。这项工作描述单芳-λ的直接合成3通过化学选择性-iodanes本位arylgermanes和arylstannanes与碘的3'-取代反应三(三氟乙酸盐)。将生成的碘化物转化为碘鎓碘化物,或在一锅中用于进一步转化。所提出的方法使多官能化的单芳基-λ的制备3 -iodanes。
