摘要：

The crystal and molecular structure of dimethyl 2-hydroxy-3-benzoylpropylphosphonate (I) has been determined. P2(t)/c, a=11.989(3), b=12.990(3), c=8.6013 Angstrom; V=1339.1(7) Angstrom(3). Molecular parameters indicate strong intramolecular interactions between the hydroxyl oxygen and the phosphorus atom. The hydrogen bonding involves the phosphoryl group as a donor, and occurs intermolecularly, yielding a dimeric arrangement of the molecules. The acid-catalyzed dehydration of 1, and the base-promoted elimination of the tosylate derivative, yielded the same (E) dimethyl 3-benzoyl-prop-2-enylphosphonate as the exclusive product.
