C-H arylation of pyridines: High regioselectivity as a consequence of the electronic character of C-H bonds and heteroarene ring
We report a new catalytic protocol for highly selective C-H arylation of pyridines containing common and synthetically versatile electron-withdrawing substituents (NO2, CN, F and Cl). The new protocol expands the scope of catalytic azine functi
Palladium-catalysed cross-coupling reactions of arylboronic acids with π-deficient heteroaryl chlorides
The palladium-catalysed cross-coupling reactions of arylboronic acids with a variety of π-deficient heteroaryl chlorides proceed in high yield. [1,4-Bis(diphenylphosphino)butane]palladium(II) dichloride was found to be a very satisfactory catalyst for monocyclic heteroaryl chlorides, whereas tetrakis(triphenylphosphine)palladium(O) was found to be excellent for a range of chloroquinoline derivatives.
