One-Pot Conversion of Aldehyde Sodium Bisulfites into Nitriles

“…[11] The adducts are not only used extensively in diverse products such as vitamin K 3 [12] and houttuynium sodium bisulfate, [13] but also in purification of thermally unstable aldehydes such as phenylacetaldehyde because aldehyde groups can be easily liberated from the bisulfite adducts when treated with acidic or basic aqueous solution. The high efficacy and ease of purification procedures prompted us to investigate application of bisulfite adducts to synthesize nitriles.…”
