Abstract

In the present study, we report the development of an efficient and spontaneous method for the preparation of Schiff bases (C1-32)
using H2SO4 as catalyst in good to excellent yields. The reaction is spontaneous when it is carried out in sequential manner, that
is, to a solution of aldehyde in methanol 2–3 drops of H2SO4 were added, to this mixture, a solution of aryl amines was added
and shaken for seconds followed by pouring into crushed ice to give solid Schiff bases in good to excellent yields. The Schiff
bases synthesized by present method are all known compounds and are characterized by their melting points, IR, and 1H-NMR
spectra’s. It is noteworthy to state that the present method is accompanied with the procedural simplicity, the efficiency and the
easy accessibility of the reaction to give the Schiff bases. We believe that this method will make a remarkable impact on the
Schiff base chemistry in the area of environmentally green chemistry.
