Abstract
The condensation of primary amines with carbonyl compounds was first reported by Schiff and condensation products often referred as Schiff bases. These bases have general structure RC=NR^’ where R and R^’ are alkyl, cyclohexyl, aryl or heterocyclic radicals which may be differently substituted.  Schiff bases are also known as anils, imines or azomethines.  Various studies have shown that >C=N- group has considerable biological importance. The presence of lone pair of electrons in a sp² hybridized orbital of nitrogen atom of the azomethine group is of considerable chemical and biological importance.
