Abstract

A Lewis/Brønsted acid-promoted intramolecular cyclization of diarylselenoethers bearing formyl groups afforded novel selenoxanthylium salts in good yield. The electronic structures of these selenoxanthylium salts were determined using NMR and UV–vis absorption spectroscopy techniques as well as DFT calculations. The obtained results clearly imply effective conjugation of the π-electrons throughout the entire fused selenium-containing heterocyclic framework.

硒醚合成硒酸盐及其电子结构

Lewis/Brønsted酸促进了含甲酰基二芳基硒醚的分子内环化，得到了收率高的新型硒黄酸盐。利用核磁共振和紫外-可见吸收光谱技术以及DFT计算确定了这些硒酸盐的电子结构。所得结果清楚地表明π电子在整个含硒杂环框架中有效共轭。

期刊介绍： Organometallics is the flagship journal of organometallic chemistry and records progress in one of the most active fields of science, bridging organic and inorganic chemistry. The journal publishes Articles, Communications, Reviews, and Tutorials (instructional overviews) that depict research on the synthesis, structure, bonding, chemical reactivity, and reaction mechanisms for a variety of applications, including catalyst design and catalytic processes; main-group, transition-metal, and lanthanide and actinide metal chemistry; synthetic aspects of polymer science and materials science; and bioorganometallic chemistry.
