Reactivity of cis-bis(acetylacetonato)dichlorotitanium(IV) towards hydroxy-containing ligands: isolation and characterisation of products

摘要

The reactivity of cis-[Ti(acac)_2Cl_2] with a number of OH containing ligands has been explored. Corresponding products have been synthesized, isolated and characterised. Three dimensional structures of some of the products were established by single crystal X-ray diffraction. The reactivity of these ligands towards non-oxo titanium centres has been found to be different from that of oxometal centres of V~v, Mo~(VI) and U~(VI), All the products of Ti~(IV) isolated were mononuclear complexes possessing one or two ligands. Both the molecular and crystal structures of the titanium products are found to be different from those of the oxometal ones.
