Metal-catalyzed coupling process comprising reacting a compound of general formula 1 with a compound A-X, to obtain a compound of general formula 2, which may further be converted to a compound of general formula 3
A one-pot, two-stepsynthesis of pyridine-2-ylmethyl thioethers is developed through a TFAA-mediated [3,3]-sigmatropic rearrangement of pyridine N-oxides and TBAB-catalyzed direct conversion of trifluoroacetates into thioethers under metal- and base-free conditions. This methodology enables thiolation of the unactivated methyl C(sp3)–H bond in 2-picolines with thiols. Remarkable features of the method

efficient and convenient rhodium catalyst system was developed for the title transformation. A base co‐catalyst was found to facilitate the key arene CH bond‐activation step and substrate scope was very broad, including both electron‐deficient pyridine N‐oxides, and electron‐rich azoles. The catalytic system was effective for the hydroheteroarylation of both alkenes and alkynes and gave excellent regio‐
