N-Alkylation of Pyromellitic Diimide: Solid-State Structure of the 1 : 1 N,N′-Diethylpyromellitic Diimide/2,6-Dimethoxynaphthalene Cocrystal

Abstract

N-Alkylation of pyromellitic diimide in the presence of CsF affords N-substituted diimide derivatives that lack the hydrogen-bonding ability of the parent diimide. The solid-state structure of the N,N′-diethylpyromellitic diimide/2,6-dimethoxynaphthalene donor{acceptor complex reveals the influence of removing this hydrogen-bonding ability on the crystal packing.
