    • Typical procedure: Under an atmosphere of dry and pure nitrogen, an oven-dried Schlenk tube equipped with a magnetic stir bar was charged with 10% w/w Pd/C (26 mg, 0.025 mmol Pd, Fluka), hydrazine hydrochloride (26 mg, 0.375 mmol), sodium hydroxide (40 mg, 1 mmol) and the aryl halide (0.5 mmol), if a solid. The tube was capped with a rubber septum. If a liquid, the aryl halide was added via syringe, followed by anhydrous toluene (1 mL). The septum was removed and the tube was sealed under a positive pressure of nitrogen. The slurry was allowed to stir for 24 h at room temperature. The reaction mixture was then diluted with dichloromethane (5 mL) and a known volume of internal standard was added. A small sample of this mixture was filtered through a plug of Celite®, washed three times with water and analyzed by gas chromatography
