(6) Synthesis of 6: Solvents used to isolate products were degased and saturated with argon. Reactants and products were protected from light. Lithium 2-lithiobenzenethiolate 4 was prepared as described elsewhere2 from thiophenol (7 g, 0.064 mol), TMEDA (22 mL, 0.142 mol), and 2.5 M n-butyllithium in hexane (57 mL, 0.142 mol). Solid 4 was isolated by filtration under argon on a medium Schlenck frit, washed with dry hexane (2 X 50 mL), and ...
