“…A dry and N 2 -flushed 10 ml-Schlenk tube, equipped with a magnetic stirring bar and a septum, was charged with a solution of (4-bromobut-3-ynyloxy) (tert-butyl)dimethylsilane (0.4 mmol), PdCl 2 (1.8 mg, 10 μmol), and neocuproine (2,9-dimethyl-1,10-phenanthrolin, 334) (4.2 mg, 20 μmol) in THF (1.5 ml) and cooled to −30 • C (Scheme 4.76) [245]. A solution of (3-((tert-butyldimethylsilyl)oxy)cyclohexyl)zinc iodide (0.42 M in THF, 1.2 ml, 0.5 mmol) was slowly added at this temperature.…”
