N-Tosylcarboxamide as a Transformable Directing Group for Pd-Catalyzed C-H Ortho-Arylation

The N-tosylcarboxamide group offers the possibility of directing the Pd-catalyzed C H arylation of arenes providing a new entry to biarylcarboxamides. Moreover, its ability to react according to different reaction conditions including intramolecular reactions makes it a pivotal directing group for a divergent synthesis of biaryl-based compounds.
