No longer a hindrance: Copper‐catalyzed electrophilicamination of arylboronicesters is accomplished under mild reaction conditions using 2.5–5.0 mol % of a catalyst derived from copper tert‐butoxide and Xantphos ligand (see scheme). The reaction tolerates a wide range of functional groups and can be used to prepare some of the most hinderedanilines made to date.
