Some compounds of -aminoketone type from benzylidene-(R)-anilines were synthesized by reaction between benzylideneanilines and methylketones (acetophenone, acetone) in the presence of hydrochloric acid as catalyst in the ethanol medium. The structure of obtained -aminoketones have been confirmed by using spectroscopic methods (IR-, 1 H- and 13 C-NMR, mass spectra). Their metallic corrosion inhibition properties also have been estimated on aluminum, copper and CT-3 steel using the immersion method.
