Crystal structure of diethyl (E)-2-[(benzo-furan-2-yl)methyl-idene]succinate.

ABSTRACT: The title compound, C17H18O5, was synthesized by a base-free catalytic Wittig reaction. The mol-ecule consists of a diethyl itaconate unit, which is connected via the C=C double bond to a benzo-furan moiety. The benzo-furan ring system (r.m.s. deviation = 0.007 Å) forms dihedral angles of 79.58 (4) and 12.12 (10)° with the mean planes through the cis and trans eth-oxy-carbonyl groups, respectively. An intra-molecular C-H⋯O hydrogen bond involving the O atom of the benzo-furan moiety is observed. In the crystal, mol-ecules are linked into ribbons running parallel to the b axis by C-H⋯O hydrogen bonds.
