Manganese (II) Chloride-Catalyzed Conjugated Addition of Amines to Electron Deficient Alkenes in Methanol-Water Medium

A simple, general and efficient method has been developed for the conjugate addition of a variety of aliphatic and aromatic amines to electron deficient alkenes in the presence of a catalytic amount of manganese (II) chloride in methanol-water to produce the corresponding β-amino derivatives in excellent yields at room temperat
