A highly efficient solvent-free protocol for the Buchwald-Hartwig amination of (hetero)aryl halides by secondary amines was developed. The reaction is mediated by a Pd(OAc)(2)/RuPhos catalytic system in air. Various (hetero) aryl halides were coupled with diaryl, alkyl-aryl, and dialkylamines in good to excellent yields (51 examples, 50-99% yield).
