trans-3,3′,4,5′-Tetra­meth­oxy­stilbene

The title compound, C(18)H(20)O(4), was synthesized by a Wittig–Horner reaction of diethyl 3,4-dimeth­oxy­benzyl­phosphate and 3,5-dimeth­oxy­benzaldehyde. In the crystal, the dihedral angle between the two aromatic rings is 2.47 (12)°. All the meth­oxy groups are almost coplanar with the aromatic r...

description The title compound, C(18)H(20)O(4), was synthesized by a Wittig–Horner reaction of diethyl 3,4-dimeth­oxy­benzyl­phosphate and 3,5-dimeth­oxy­benzaldehyde. In the crystal, the dihedral angle between the two aromatic rings is 2.47 (12)°. All the meth­oxy groups are almost coplanar with the aromatic ring to which they are attached [C—C—O—C torsion angles = −2.8 (3), −5.2 (4), −176.3 (2) and −178.0 (2)°].
