Abstract
An array of amides can be cross-coupled with a range of arylboronic acids in very good yields using a commercially available, air- and moisture-stable Pd-PEPPSI-IPr complex as a highly reactive precatalyst in a single, operationally simple protocol. Pd-PEPPSI-IPr provides a significant improvement over all current Pd/phosphane catalysts for amide N-C bond activation.
