Synthesis, characterisation and adduct formation of (3,4-dimethylphenoxo)tantalum(V) chlorides

New 3,4-dimethylphenoxotantalum(V) chlorides of the type Ta(OC6H3Me2-3,4)xCl5-x (1a-c), (where x = 1,2,3) have been synthesized by the interaction of tantalum(V) chloride and 3,4-dimethylphenol in benzene (or dichloromethane), under refluxing conditions.Treatment of 1a-c with donor ligands such as pyridine (Py) or tetrahydrofuran (THF) yields molecular adducts of the types, Ta(OC6H3Me3-3,4)xCl5-x(Py) (2a-c) and Ta(OC6H3Me2-3,4)xCl5-x (THF) (3a-c) (x = 1,2,3).Interaction of sodium 3,4-dimethylphenolate with TaCl5 in THF and benzene in different stoichiometric ratios yields adducts of the type Ta(OC6H3Me2-3,4)xCl5-x (THF) (3c-e) (x = 3,4,5).These derivatives have been characterized by elemental analyses, IR and PMR spectral data as well as molecular weight determinations.
