実験手順
Into a 100 ml flask equipped with magnetic stirrer were placed 2.45 g (0.01 mol) of 4-nitrophenylsulfonylacetic acid and 50 ml of acetone. Stirring was begun and upon dissolution of the acid, 4.0 g of a 25% methanolic solution (i.e., 1.00 g, 0.011 mol) of tetramethylammonium hydroxide was slowly added, dropwise over a 15 min period. A precipitate formed in the dark red solution. Filtration, washing with acetone (10 ml) and drying in air afforded 2.9 g (91%) of tetramethylammonium 4-nitrophenylsulfonylacetate (Compound C1-A1). 1H and 13C NMR were in agreement with the proposed structure.
