Abstract
The title compound, 2-(1-phenyl-l,3-butadien-2-yl)benzoic acid, C6HsCH~-------C(C6H4COOH)CH~-----CH2 (or C17HI402) , has been obtained as the major product from an indium-mediated coupling of benzaldehyde with methyl o-(3-bromo-1-propynyl)benzoate. The compound crystallizes as centrosymmetric hydrogen-bonded dimers. The diene portion is in the s-trans conformation, with the aromatic groups cis to one another.
