通过使用锂化的杂环,芳基或杂芳基硼酸酯和亲电卤素源,通过无过渡金属的sp2-sp2交叉偶联策略,可以实现多种杂芳基芳基化合物的合成。杂二芳基的构建是通过亲电活化芳基-杂芳基硼酸酯络合物进行的,这引发了1,2-从硼向碳原子的迁移。中间体硼酸酯的随后氧化以良好的产率提供了杂联二芳基。已经进行了全面的11 B NMR研究以支持该机理。在没有过渡金属的情况下,两个亲核交叉偶联伙伴之间的交叉偶联显示了可靠的歧管,可以以高收率获得杂二芳基。呋喃,噻吩,苯并呋喃,苯并噻吩和吲哚等各种杂环具有良好的耐受性。最后,

metal dichalcogenides that have catalytically active edge functional groups was described. The terminal sulfur groups could effectively catalyze a formation of an azo-linked intermediate with aryl diazonium salts, leading to produce heteroarenes with good yields. This novel methodology using bulk 2D transition metal dichalcogenides that have catalytically active edge functional groups can apply for various

Perylenequinonoid-catalyzed photoredox activation for the direct arylation of (het)arenes with sunlight
and photobiology. However, their applications in photocatalysis are yet to be explored. We report here that sunlight along with 1 mol% cercosporin, which is one of the perylenequinonoid pigments, catalyzes the direct C–H bond arylation of (het)arenes by a photoredox process with good regioselectivity and broad functional group compatibility. Furthermore, a gram-scale reaction with great conversions
