A novel reaction involving cyano transfer from benzophenone cyanohydrin to aldehydes and imines was realized by usingdibutyltindimethoxide as a catalyst. Various cyanohydrins and α-amino nitriles were obtained in moderate to high yields by this reaction. Ketimines also showed remarkable reactivity as cyano acceptors under conventional reaction conditions. This catalytic reaction was further applied

An efficient, safe, and environmentally friendly tertiary butyl hydrogen peroxide (TBHP)-mediated rearrangement of aryl/alkylidenemalononitrile with anilines has been developed with in situ generation of HCN as the cyanide source for the synthesis of substituted α-aminonitriles and α-aminoamide. A diverse set of α-aminonitriles and α-aminoamides was efficiently synthesized in good to excellent yields
