摘要

我们开发了一种 "OFF/ON "电流切换方案,作为一锅有机合成的新策略。在电化学电池中,无需施加电流即可实现 2-溴吡啶与芳基硼酸的 Suzuki-Miyaura 偶联,随后利用已存在的 Pd 催化剂进行 Pd 催化的电化学 C-H 溴化反应,得到 2-(2-溴芳基)吡啶作为产物。在第二步中,无需添加外部溴源,也可实现溴代烯烃的一锅合成。此外,OFF/ON/OFF 两次切换方案还实现了含 N 的萜芳基衍生物的形成。

Off/on Switching of Electric Current as a Strategy for One-Pot Synthesis of Bromoarylpyridines by Cross-Coupling/ C−H Bromination

An “OFF/ON” electric current switching protocol was developed as a new strategy for one-pot organic synthesis. Suzuki-Miyaura coupling of 2-bromopyridines with arylboronic acids in an electrochemical cell was performed without applying an electric current, and subsequently, the Pd-catalyzed electrochemical C−H bromination was conducted using the already-present Pd catalyst to obtain 2-(2-bromoaryl)pyridines as products. The one-pot synthesis of bromoarenes can also be achieved without adding an external Br source in the second step. Furthermore, an OFF/ON/OFF two-times switching protocol also realized the formation of an N-containing teraryl derivative.

期刊介绍: The fledgling State of Israel began to publish its scientific activity in 1951 under the general heading of Bulletin of the Research Council of Israel, which quickly split into sections to accommodate various fields in the growing academic community. In 1963, the Bulletin ceased publication and independent journals were born, with Section A becoming the new Israel Journal of Chemistry. The Israel Journal of Chemistry is the official journal of the Israel Chemical Society. Effective from Volume 50 (2010) it is published by Wiley-VCH. The Israel Journal of Chemistry is an international and peer-reviewed publication forum for Special Issues on timely research topics in all fields of chemistry: from biochemistry through organic and inorganic chemistry to polymer, physical and theoretical chemistry, including all interdisciplinary topics. Each topical issue is edited by one or several Guest Editors and primarily contains invited Review articles. Communications and Full Papers may be published occasionally, if they fit with the quality standards of the journal. The publication language is English and the journal is published twelve times a year.
