cyanate in dried chloroform was found to give hypervalent isocyanato-iodine(III) reagent 5 in excellent yield, while the oxo-bridged 1,1′-oxybis(2-acetyl-1,2-dihydro-3H-1λ3-benzo[d][1,2]iodaz-ol-3-one) 6 was obtained when a mixture of chloroform and water was used as solvent. Structure of these two hypervalent iodine reagents were established by X-ray crystallography and their reaction with base, aniline
发现用干燥氯仿中的氰酸银处理 2-乙酰基-1-氯-1,2-二氢-3 H -1λ 3 -苯并[ d ][1,2]碘唑-3-酮1f得到高价异氰酸基-碘(III) 试剂5的收率极佳,而氧桥 1,1'-氧双(2-乙酰基-1,2-二氢-3 H -1λ 3 -苯并[ d ][1,2]碘偶氮醇-3-一)6当使用氯仿和水的混合物作为溶剂时得到。通过X射线晶体学确定了这两种高价碘试剂的结构,并研究了它们与碱、苯胺、甲醇和环醚的反应。重新审视了先前报道的 1-氰基苯并阿酮化合物并修改了其结构。
