Selective copper-promoted cross-coupling reaction of anilines and alkylboranes

Autor: Leticia Naya, Jacobo Cruces, Marta Larrosa, Ramón Rodríguez

Publikováno v: Tetrahedron Letters. 53:769-772

Extension of the Chan–Lam N-alkylation of anilines by using alkylboranes as organoboron partners is reported. Alkylboranes, synthesized by hydroboration of styrenes, are effectively coupled with anilines, which comprises a facile method for the syn
