摘要

已经开发了一种从现成且易于处理的氧化苯larsin和Tf2O生成砷化当量的策略。原位生成的阳离子等价物可以通过分子间和分子内C-As键的连续形成，与双芳基硼酸盐反应，直接生成其他方法难以制备的相应的二苯并甲醚。此外，二苯甲醚中独特的氧原子插入到C-As键中，形成相应的[1,2]草精氨酸衍生物。

Synthesis of dibenzoarsole derivatives from biarylborates via the twofold formation of C–As bonds using arsenium dication equivalents

A strategy for the generation of arsenium dication equivalents from readily available and easy-to-handle phenylarsine oxide and Tf₂O has been developed. The in-situ-generated dication equivalent can react with biarylborates to directly produce the corresponding dibenzoarsoles, which are difficult to prepare by other means, via the successive formation of inter- and intramolecular C-As bonds. Furthermore, the unique oxygen atom insertion into the C–As bond in the dibenzoarsole is developed to form the corresponding [1,2]oxarsinine derivative.

期刊介绍： Chemical Science is a journal that encompasses various disciplines within the chemical sciences. Its scope includes publishing ground-breaking research with significant implications for its respective field, as well as appealing to a wider audience in related areas. To be considered for publication, articles must showcase innovative and original advances in their field of study and be presented in a manner that is understandable to scientists from diverse backgrounds. However, the journal generally does not publish highly specialized research.
