General procedure: Arylchloride (1 mmol, 1 equiv), decane (internal standard, 0.2 mL), and anhydrous Et2O (5 mL) were sequentially added to a pre-dried Schlenk flask equipped with a magnetic stirrer and a rubber septum under argon. The flask was cooled to ?95°C (methanol/liquid nitrogen bath) followed by the dropwise addition of a previously prepared LiDBB solution (ca. 0.25 M in THF, 2 mmol, 8 mL, 2 equiv). After addition and stirring for 5 min at this temperature, aryllithium reagent 2 was obtained. The corresponding arylzinc reagent 5 was prepared by the addition of ZnCl2 solution (1.0 M in THF, 1 mmol, 1 mL) followed by warming to r.t. The yield of the aryllithium or arylzinc reagent was determined by GC analysis of an aliquot of the resulting arylzinc reagent quenched with asolution of iodine in anhydrous THF in the presence of an internal standard (decane).
