Suppose that each of the following pairs of compounds are being used as reactants in this experiment. Draw structures of the intermediate imines formed, as well as the final amine product. A. cinnamaldehyde and aniline B. benzaldehyde and m-nitroaniline C. benzaldehyde and aniline D. cyclohexanone and aniline Then ... Propose a mechanism to show how the imine intermediate can be converted back into the original reactants through the addition of water. Draw electron movement with arrows and show intermediates with charges, partial polarization and nucleophiles and electrophiles
