trans-1-Cyano-2-(2-methoxyphenyl)-1-nitroethylene

Abstract

The title compound, C(10)H(8)N(2)O(3), has been prepared by condensation of 2-methoxybenzaldehyde and nitroacetonitrile in ethanol at room temperature. Its investigation has been undertaken as a part of search for new nonlinear optical compounds. The pi-conjugated molecule is almost planar. Molecules in the crystal are packed in stacks with antiparallel molecular orientation and slightly alternating distances between mean molecular planes.

Aryl(hetaryl)-containing gem-cyanonitroethenes: Synthesis, structure, and reactions with 2,3-dimethyl-1,3-butadiene

“…The X-ray analysis data of α-nitrocinnamic acid nitrile, its derivatives (ortho-and para-methoxysubstituted at the benzene ring), and gem-cyanonitroethene of ferrocene type available in the literature have confirmed the molecules E-configuration in the crystal [7,28,36,37].…”

(2Z)-3-(4-Hydroxyphenyl)-2-(pyridinium-4-yl)acrylonitrilep-toluenesulfonate

“…The present investigation is a continuation of our work that includes the synthesis and structural studies of polarized organic compounds with potential nonlinear optical properties (Huang et al, 1999;Nesterov, Kislyi et al, 2000;Wang et al, 2001;Helvenston et al, 2005). These compounds may have applications in nonlinear optical, electrooptical, photorefractive and optical limiting materials (Zyss et al, 1994;Kuzyk & Dirk, 1998;Kaino et al, 2002).…”

Chemistry of 2-aryl-1-cyano-1-nitroethenes. Part I. Synthesis and physical properties

“…An analogous methodology was also applied later in the case of ACNs 2, 7, 10, 14, 15, 23 and 25 [21][22][23][24]. Later [18,[25][26][27]28], other aliphatic and alicyclic amines (n-propylamine, n-pentylamine, morpholine, ethylenediamine, β-alanine) were also tested as catalysts in similar syntheses. In these syntheses several new compounds were prepared.…”
