摘要:
                                N-Cyanoimides are useful precursors to N-alkyl or N-aryl imides.  Treatment of aromatic N-cyanoimides such as N-cyanophthalimide (1) with primary amines provides N-substituted imides directly, while aliphatic N-cyanoimides afford diamide intermediates which can be converted to N-substituted imides upon heating.
