Kubota, Koji;Takahashi, Rikuro;Uesugi, Minami;Ito, Hajime research published 《 A Glove-Box- and Schlenk-Line-Free Protocol for Solid-State C-N Cross-Coupling Reactions Using Mechanochemistry》, the research content is summarized as follows. Carbon-nitrogen (C-N) bond-forming cross-coupling reactions catalyzed by palladium-based catalysts, the so-called Buchwald-Hartwig aminations, have been widely employed for the synthesis of pharmaceuticals and aryl-amine-based organic materials in academic and industrial settings. However, in solution, these reactions usually require glove-box and Schlenk line techniques, which greatly reduces their practical utility. Here, we report the development of operationally simple mechanochem. C-N cross-coupling reactions in the solid-state. Intensive investigations of various ball milling parameters revealed that the air-stable ligand tri(1-adamantyl)phosphine can be used to achieve solid-state coupling reactions between aryl halides and diarylamines with high efficiency. Notably, all exptl. operations of the developed protocol can be carried out in air, thus providing a more convenient, industrially attractive, and sustainable alternative to conventional solution-based palladium-catalyzed C-N coupling reactions. The development of operationally simple mechanochem. solid-state C-N cross-coupling reactions in air is reported.
19111-87-6, 2-Bromotriphenylene is a useful research compound. Its molecular formula is C18H11Br and its molecular weight is 307.2 g/mol. The purity is usually 95%.
2-Bromotriphenylene is a brominating agent that has the ability to react with sodium carbonate and emit light. The luminescence of 2-bromotriphenylene can be used as an indicator of the degree of dilution, or how much water is present in a solution. It also emits light when it reacts with chloride ions in a reaction solution. 2-Bromotriphenylene can be used as a polymer matrix to form polymeric films, which are then used as catalysts for organic reactions. The luminescence properties of 2-bromotriphenylene make it suitable for use in functional theory experiments. This chemical compound is relatively low cost, and has been shown to have high yield in catalysis., Product Details of C18H11Br
