Noncatalytic Pyridyl-Directed Alkylation and Arylation Carbon–Fluorine Bond of Polyfluoroarenes with Grignard Reagents
摘要:
Cross-coupling reaction of polyfluoroarenes with Grignard reagents via pyridine-directed cleavage of C-F bond in the absence of metal catalysts was developed. A possible mechanism was suggested.
The Rh(I)-catalyzed direct reorganization of organic frameworks and group exchanges between carboxylic acids and aryl ketones was developed with the assistance of directinggroup. Biaryls, alkenylarenes, and alkylarenes were produced in high efficiency from aryl ketones and the corresponding carboxylic acids by releasing the other molecule of carboxylic acids and carbon monoxide. A wide range of functional
