Abstract
An efficient, safe, and environmentally friendly TBHP-mediated rearrangement of aryl/alkylidene malononitrile with anilines produces in situ HCN as the cyanide source for the synthesis of substituted α-aminonitriles and α-aminoamides in very good yields. This method features good functional group tolerance, and the in situ-generated HCN bypasses the use of an external cyanide source.
