4-(2-Bromo-4,5-dimethoxybenzyloxy)phthalonitrile

Abstract

The title phthalonitrile derivative, C17H13BrN2O3, contains two aromatic rings, which are nearly coplanar. The crystal structure is stabilized by C—H⋯O hydrogen‐bond inter­actions.

4-[2-(Cyclohexa-1,4-dien-1-yl)ethoxy]benzene-1,2-dicarbonitrile

“…The C=C double bonds of the cyclohexa-1,4-dienyl ring measure 1.344 (3) Å and 1.319 (4) Å and are similar to those in other works (Dialer et al, 2004;Jandacek & Simonsen, 1969;Therrien & Süss-Fink, 2006;Lou & Hu, 2009). The C15≡N1 and C16≡N2 triple bonds, which are placed at meta and para position, are 1.141 (2) Å, and in good agreement with literature values (Subbiah Pandi et al, 2002;Yu et al, 2010;Nesi et al, 1998;Ocak Ískeleli et al, 2005).…”
