Ethyl 5-oxo-2,3-diphenylcyclopentane-1-carboxylate
The title compound, C20H20O3, was prepared by an acyloin-type condensation reaction in the presence of sodium sand and dry ether using ethyl cinnamate as the starting material. The C—O bond lengths for the carbonyl groups are 1.191 (2) and 1.198 (2)&...

| description | The title compound, C20H20O3, was prepared by an acyloin-type condensation reaction in the presence of sodium sand and dry ether using ethyl cinnamate as the starting material. The C—O bond lengths for the carbonyl groups are 1.191 (2) and 1.198 (2) Å, while the C—O bond in the ester group is 1.335 (2) Å. The C—C bond lengths in the phenyl groups average 1.375 Å, while the C—C bonds in the cyclopentanone ring average 1.525 Å, indicating single C—C bonds in the latter. |
