4,5-Bis(4-methoxyphenoxy)phthalonitrile

Abstract

The title compound, C22H16N2O4, was obtained unintentionally as the product of an attempted synthesis of a new phthalocyanine. The dihedral angles formed by the central benzene ring with the aromatic rings of the meth­oxy­phen­oxy groups are 85.39 (5) and 64.19 (5)°.

4,5-Diphenoxybenzene-1,2-dicarbonitrile

“…The (C9-C14) and (C15-C20) rings form a dihedral angle of 73.68 (15) and 84.65 (15)°, respectively with the (C1-C6) ring. The molecular conformation observed in (I) resembles closely that reported for the p-methoxy derivative (Yu et al, 2010).…”

For a related structure, see: Yu et al (2010). The present synthesis is based on earlier syntheses; see: Wohrle et al (1993); Li et al (2008).…”
