(Dicyano)iodonium triflate (NC)2I+−OTf can be prepared by the reaction of O=I-OTf with cyanotrimethylsilane and isolated as an air sensitive crystalline solid unstable at room temperature. This compound generated in situ reacts with tributyltin derivatives of various aromatic compounds or acetylenes at −40 °C forming the corresponding iodoniumsalts in good yield.
可以通过O = I-OTf与氰基三甲基硅烷的反应来制备三氟甲磺酸(二氰基)碘鎓(NC)2 I + -OTf,并分离为在室温下不稳定的对空气敏感的结晶固体。该原位生成的化合物在-40°C下与各种芳族化合物或乙炔的三丁基锡衍生物反应,形成相应的碘鎓盐,收率很高。
