Crystal Structure of 2,3-Bis(4-methoxycarbonylphenyl)-naphthalene-1,4-dione

Abstract

The title compound was prepared by means of Meerwein arylation of naphthalene-1,4-dione (1,4-naphthoquinone). From crystallographic studies, two aryl rings of the title compound were found to exist in a bis-pseudoorthogonal orientation to the quinone ring both in solution and the gas phase (previouly reported by us), indicating its potential utility as a hinge spacer for constructing macrocyclic host compounds.
