Abstract

Abstract 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).
