    • note
    • 15N nmr data collected for compounds 1a-j [14] show that electron-donating and electron-repelling substituents cause an upfield shift for the N(1) nitrogen atom in contrast to the electron-withdrawing substituents.

    • note
    • The nmr measurements for N-phenylsubstituted acetamides [19] show that substituents affect more strongly the electron density on the oxygen atom than those on the nitrogen atom.
