cyanohydrins. Among them, the cyanosilylation of carbonylcompounds using trimethylsilyl cyanide (TMSCN) is widely utilized for the synthesis of cyanohydrins. Several reagents including Lewis acids, Lewis bases, metal alkoxides, bifunctional catalysts, iodine and inorganic salts have been found to effectively transfer the cyano group from TMSCN to carbonylcompounds. Various types of Lewis acids such as AlCl3

Abstract The alkali salt of L-proline was demonstrated to be an efficient and practical catalyst for the cyanosilylation of a wide variety of simple and functionalized carbonylcompoundsundersolvent-freeconditions. The reactions proceeded smoothly at room temperature to afford the corresponding cyanohydrins in good to excellent yields.
