Boric Acid → 3-(4-Methoxyphenylsulfonyl)acrylonitrile

Participants

Reaction Steps

In a flask, 59.5 g. (0.31 mole) sodium 4-methoxybenzenesulfinate, 25.4 g. (0.31 mole) sodium acetate and 19.2 g. (0.31 mole) boric acid were dissolved in a mixture of 150 ml. water and 275 ml. isopropyl alcohol. There was then added, with stirring, dropwise, 33.9 g. (31 ml., 0.39 mole) 2-chloroacrylonitrile. The mixture was stirred for some time at room temperature. Water was then added and the mixture stirred for one hour. A precipitate formed, which was filtered, washed with water and ethanol, and dried.
