Abstract
A ligandless and base-free cross-coupling of arylboronic acids and potassium aryltrifluoroborate salts with primary and secondary aliphatic amines and anilines utilizes catalytic copper(II) acetate monohydrate and molecular sieves in dichloromethane at slightly elevated temperatures under an atmosphere of oxygen and tolerates a broad range of functional groups.
