참여 물질

반응 단계

2-Bromonaphthalene (0.08 moles, 16.6 g), 4-nitrothiophenol (0.08 moles, 12.4 g), potassium carbonate (0.1 moles, 13.4 g), copper bronze (6.0 g) and cuprous chloride (0.02 moles, 2.0 g) were heated under reflux for 4 days in 300 ml pyridine. The solution was filtered hot, concentrated, dissolved in ethyl acetate and washed thoroughly with 2N HCl and water. The solution was dried over sodium sulfate, concentrated and purified by HPLC over silica gel eluted with 5% ethyl acetate in hexane. The product was recrystallized from ethyl acetate and hexane to yield 2-(4-nitrophenylthio)naphthalene 2.6 g, 12% in the first crop. Mass spec. (FD) 281.
