A detailed mechanism study on the anion ligand promoted selective C-H bond fluorination is reported. The role of the anion ligand has been clarified by experimental evidence and DFT calculations. Moreover, the nitrate promoted C-F bond reductive elimination enabled a selective C-H bond fluorination of various symmetric and asymmetric azobenzenes to access diverse o-fluoroanilines.

, (2016/11/24)
The invention discloses a synthetic method for 3-amino-4-fluorophenylboronic acid. The method includes the steps of conducting bromination on o-fluoronitrobenzene, conducting reduction to generate 5-bromo-2-fluoroanil, making 5-bromo-2-fluoroanil and tetrahydroxydiboron react in a coupled mode to generate the product, namely, 3-amino-4-fluorophenylboronic acid. According to the method, raw materials can be easily obtained, and operation is easy and convenient. The method is an appropriate route for preparing 3-amino-4-fluorophenylboronic acid.
