실험 절차

A solution of 34 g (0.179 mole) of 2-p-anisylthiophene in 500 ml of carbon tetrachloride was treated with 23 ml (28.5 g, 0.197 mole) of benzenesulfenyl chloride and 0.1 g of iron powder. The mixture was allowed to stand at room temperature for eight days. The mixture was filtered to remove a small amount of solid. The filtrate was evaporated to give 67 g of crude solid product. Recrystallization from 220 ml of ethyl acetate gave 15.4 g (29%) of 2-p-anisyl-5-(phenylthio)thiophene, m.p. 92°-93° C.
