An efficient and eco-friendly method for hydrocyanation of sulfonylimines via one-pot two-step procedure using potassium hexacyanoferrate(II) as a cyanide source, benzoyl chloride as a promoter, and potassium carbonate as a base is described. This protocol has the features of using nontoxic, nonvolatile and inexpensive cyanide source, high yield, and simple work-up procedure.
描述了一种高效且生态友好的方法,该方法使用六氰合铁酸钾(II)作为氰化物源,苯甲酰氯作为促进剂,碳酸钾作为碱,通过一锅两步程序进行磺酰亚胺的氢氰化。该协议的特点是使用无毒,不挥发和廉价的氰化物源,高收率和简单的后处理程序。
