Generally applicable, palladium-catalyzeddirectarylations of 1,2,3-triazoles with aryl chlorides were accomplished through conventional heating at reaction temperatures of 105–120 °C. Thereby, intra- and intermolecular CH bond functionalizations were achieved with a variety of differently substituted chlorides as electrophiles, bearing numerous valuable functional groups.

Ruthenium(II)-catalyzed cross-dehydrogenative C–H alkenylations by triazole assistance

Ruthenium(II) carboxylate complexes allowed for efficient cross-dehydrogenative alkenylations of N-aryl-1,2,3-triazoles. The twofold C-H functionalizations occurred with excellent chemo-, regio-, site- and diastereoselectivities, and ample substrate scope. The versatile ruthenium(II) catalyst proved tolerant of moisture, air, and various electrophilic functional groups. Mechanistic studies were in good agreement with an initial C-H metalation by a cationic ruthenium(II) carboxylate, along with a subsequent migratory insertion of the olefin. (C) 2015 Elsevier Ltd.
