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.

transition-metal-free, and direct decarboxylative arylation of 2-picolinic acids with simple arenes is described. The oxidativedecarboxylative arylation of 2-picolinic acids with arenes proceeds readily via N-chloro carbene intermediates to afford 2-arylpyridines in satisfactory to good yields under transition-metal-free conditions. This new type of decarboxylative arylation is operationally simple

Disclosed are a monomer of iridium complex having a fluoro group as a functional group, a monomer of carbazole derivative having a hydroxy group as the functional group, and a copolymer containing the monomers in its main chain. The iridium complex used as a phosphorescent material and the carbazole derivative having an excellent hole transporting capability are synthesized as the monomer to form the copolymer. The content of iridium complex is easily controlled, and the carbazole derivative and iridium complex are contained in the main chain during the copolymer formation, thereby capable of manufacturing a light emitting device with higher heat resistance and chemical stability.
