%Amino-/.%arylacrylonitriles are commonly prepared by the nucleophilicadditionreaction of acetonitrile anion, prepared by in-situ deprotonation of acetonitrile, to aromatic nitriles. As acetonitrile is a very weak acid (pKa = 31.3)", strong bases such as r-BuOK'? or NaNH2 are The nucleophilicreactions usually give poor yields and require long reaction times (at least 10 hrs). Application of Ultrasonically
