摘要：
The intracomplex conversion of (2-diphenylphosphanoethyl)cyclopentadienyl zirconium and titanium complexes into the corresponding 2-phosphinothioyl and 2-phosphinoyl derivatives, viz., (η5-C5H5)[η 5-C5H4CH2CH2P(S)Ph2]ZrCl2, [η5-C5H4CH2CH2P(S)Ph2]ZrCl3, [η5:η1C5H4CH2CH2P(O)Ph2]ZrCl3·THF, and [η5:η 1-C5H4CH2CH2P(O)Ph2]TiCl3 (7), was performed. The NMR spectroscopy data revealed the following order of the coordination ability of the functional groups with respect to the Zr center: Ph2P=O > Ph2P > Ph2P=S. An analogous order was found for the monodentate ligands (Ph3P=O > Ph3P > Ph3P=S) with respect to (η5-C5H5)ZrCl3. The molecular structure of complex 7 was established by X-ray diffraction analysis. Coordination of the Ph2P=O group to the titanium atom was found retained both in the crystalline state and solution.
