Abstract
The development and validation of copper-catalyzed, electrophilic amination of aryl and heteroaryl organolithiums with N,N-dialkyl-O-benzoylhydroxylamines have been achieved exploiting recoverable siloxane transfer agents. Given the ready availability of organolithium compounds, the mild reaction conditions, the ease of product purification, and the ready recovery of the siloxane transfer agents, this transformation comprises a useful tactic to access diverse aryl and heteroaryl amines.
