(E)-Methyl 2-[(2-formyl-6-meth-oxy-phen-oxy)meth-yl]-3-phenyl-acrylate.

ABSTRACT: The title compound, C(19)H(18)O(5), crystallizes with two independent mol-ecules (A and B) in an asymmetric unit in both of which the two aromatic rings are in a bis-ectional orientation as evidenced by the dihedral angle between them [41.7?(1)° in mol-ecule A and 35.6?(1)° in mol-ecule B]. Both mol-ecules adopt an E configuration with respect to the C=C bond. An intra-molecular C-H?O hydrogen-bond occurs in mol-ecule A. The crystal packing features inter-molecular C-H?O inter-actions.

Methyl (E)-2-[(2-nitro-phen-oxy)meth-yl]-3-phenyl-acrylate.

Project description:The title compound, C(17)H(15)NO(5), adopts an E conformation with respect to the C=C double bond of the phenyl-acrylate unit. The phenyl ring and methyl acrylate group of the phenyl-acrylate unit are disordered over two sets of sites with site-occupancy ratios of 0.705?(5):0.295?(5) and 0.683?(3):0.317?(3), respectively. The mean plane through the benzene ring of the phenyl acrylate makes dihedral angles of 88.4?(8) (major component) and 86.7?(8)° (minor component) with the nitro-phen-oxy ring; the dihedral angle between the two components is 3.64?(6)°. Intra-molecular C-H?O interactions stabilise the molecular structure. In the crystal, C-H?O inter-actions result in a chain of mol-ecules running along the b axis.

Project description:In the title compound, C(19)H(17)BrO(4), the dihedral angle between the two benzene rings is 82.1?(1)°.
