摘要

通过使用易于获得的硫氰酸盐和硒氰酸盐，描述了一种用于将SCN和SeCN基团直接引入不同取代的吲哚和咔唑的简便的选择性氟介导氧化方法，并通过提供24个示例来强调该方法的范围。证明了在咔唑骨架上依次引入SCN和SeCN并合成相应的s -四唑和se -四唑衍生物的可行性。

An Efficient Selectfluor-Mediated Oxidative Thio- and Selenocyanation of Diversely Substituted Indoles and Carbazoles

A facile Selectfluor-mediated oxidative method for direct introduction of SCN and SeCN groups into diversely substituted indoles and carbazoles is described, by employing readily available thiocyanate and selenocyanate salts, and the scope of the method is underscored by providing 24 examples. The feasibility to sequentially introduce SCN followed by SeCN on a carbazole framework and to synthesize the corresponding S-tetrazole and Se-tetrazole derivatives is also demonstrated.

期刊介绍： Heteroatom Chemistry brings together a broad, interdisciplinary group of chemists who work with compounds containing main-group elements of groups 13 through 17 of the Periodic Table, and certain other related elements. The fundamental reactivity under investigation should, in all cases, be concentrated about the heteroatoms. It does not matter whether the compounds being studied are acyclic or cyclic; saturated or unsaturated; monomeric, polymeric or solid state in nature; inorganic, organic, or naturally occurring, so long as the heteroatom is playing an essential role. Computational, experimental, and combined studies are equally welcome. Subject areas include (but are by no means limited to): -Reactivity about heteroatoms for accessing new products or synthetic pathways -Unusual valency main-group element compounds and their properties -Highly strained (e.g. bridged) main-group element compounds and their properties -Photochemical or thermal cleavage of heteroatom bonds and the resulting reactivity -Uncommon and structurally interesting heteroatom-containing species (including those containing multiple bonds and catenation) -Stereochemistry of compounds due to the presence of heteroatoms -Neighboring group effects of heteroatoms on the properties of compounds -Main-group element compounds as analogues of transition metal compounds -Variations and new results from established and named reactions (including Wittig, Kabachnik–Fields, Pudovik, Arbuzov, Hirao, and Mitsunobu) -Catalysis and green syntheses enabled by heteroatoms and their chemistry -Applications of compounds where the heteroatom plays a critical role. In addition to original research articles on heteroatom chemistry, the journal welcomes focused review articles that examine the state of the art, identify emerging trends, and suggest future directions for developing fields.
