Copper(II) Triflate Catalyzed Intermolecular Aromatic Substitution of <i>N</i>,<i>N</i>‐Disubstituted Anilines with Diazo Esters

Abstract

Abstract The intermolecular aromatic substitution of N , N ‐disubstituted anilines with diazo esters is achieved under mild conditions in the presence of a catalytic amount of copper(II) triflate (up to 89 % yield). The scope and limitations regarding substrates, diazo esters, and ligands in this reaction are described.
