Abstract

Methods to construct the carbon-nitrogen bond in aryl amines are limited, rely on high temperatures, mechanistically illdefined copper mediated processes, lJ occur under the highly reducing conditions of SRN 1 reaction^,^ or provide nonregiospecific products by way of aryne intermediates? Ten years ago, it was noted that palladium compounds can catalyze the regiospecific formation of aryl amines from aryl halides and the weakly nucleophilic tin ...
