Reactions of N‐aminophthalimide with electrophiles. II. Preparation and properties of araldehyde hydrazones

Abstract N ‐Aminophthalimide (I) reacted with a variety of aromatic aldehydes to give the related arylideneaminophthalimides (III‐X), although typical ketones such as acetone and benzophenone did not under the specific conditions employed. Catalytic reduction of benzylideneaminophthalimide (III) led to N ‐benzylaminophthalimide (XI), a stable acid‐free precursor of benzylhydrazine.
