title: Copper-promoted N-cyclopropylation of anilines and amines by cyclopropylboronic acid.
abstract: Reaction of anilines, primary and secondary aliphatic amines with cyclopropylboronic acid in dichloroethane in the presence of Cu(OAc)(2) (1 equiv.), 2,2'-bipyridine (1 equiv.) and sodium carbonate or sodium bicarbonate (2 equiv.) under air atmosphere afforded the corresponding N-cyclopropyl derivatives in good to excellent yields.
