    • 2 (1 mol %), ligand (2 mol %), N-benzylpiperazine (1.5 mmol), (hetero)aryl halide (1.25 mmol), and hexadecane (100 μL; as internal standard for GC) were transferred subsequently from inert stock solutions (anhydrous toluene) and diluted with anhydrous toluene (total volume of toluene: 3 mL). The reactor was kept shaking with 350 rpm over 20 h at 110 °C. After cooling to rt and automatical filtration using a cleavage block, reaction mixtures were removed from reactor, analyzed by GC and/or chromatographed on silica using eluent mixtures of hexane/ethyl acetate in different ratios. The identity of the products was confirmed by GC-MS and NMR data.
