摘要：

The title compound has been shown by H-1 and C-13 NMR spectroscopy to exist in solution as an enol/keto mixture, with an isomer ratio at ambient temperature in chloroform of approx. 17:1. CP-MAS C-13 NMR spectroscopy shows that only the enol form occurs in the crystalline state. This conclusion was confirmed by a single crystal X-ray structure determination. The O-C-C-C-O fragment of the molecule is planar, with an asymmetric intramolecular hydrogen bond; there are no intermolecular hydrogen bonds.
