Reaction Conditions

Reaction Steps

To a solution of thiophene (2.1 g, 25.0 mmol) in anhydrous THF (50 mL) was added dropwise over 30 minutes at −38° C. t-butyllithium in pentane (1.6 M, 16.0 mL, 25.6 mmol). The solution was stirred for 1 h at −38° C. and then cooled to −78° C. Trimethyltin chloride in THF (1 M, 25.3 mL, 25.3 mmol) was added dropwise over 30 min. The reaction was then stirred for 2 h at −78° C. and then for 15 h at r.t. The solvent was evaporated and the resulting yellow solid was taken up in other, washed with water and dried Na2SO4 and then evaporated to give a light brown liquid which solidified on standing.
