Mechanochemical synthesis of phthalimides with crystal structures of intermediates and products

Abstract

A series of phthalimides have been successfully synthesized in the solid state by grinding (or kneading) of substituted phthalic anhydride and aniline derivatives. Selected products and intermediates were crystallized and characterized by crystallography leading to a potential rationale for the solid-state reactivity that suggests that co-crystals could serve as intermediates.
