Interaction of and with HOR1 (R1 = C6H2But2-2,6-Me-4) allows for the isolation of 1)(NMe3)> 1 and 1)(NMe3)> 2 respectively.Compound 1 exists in both mono- and di-meric forms in the solid state.The reaction of 1 with NH2But results in ligand redistribution to give 1)2(NH2But)> 3.Similarly, multiple recrystallisation of 1 from Et2O allows for the isolation of 1)2(OEt2)> 4, while addition of HOR2 (R2 = C6H3Ph2-2,6) to 1 yields the mixed aryloxide complex 1)(OR2)(NMe3)> 5.Interaction of compound 1 with benzophenone results in the formation of the bridged dimer <1)(μ-OCHPh2)>2> 6.The reaction of 3 molar equivalents of HOR1 with LiAlH4 yields, in addition to <1)(OEt2)>2>, compound 4, which reacts further with H2O, HOR1 or NH2C6H2Cl3-2,4,6 to give <1)2>2> 7, 1)3> 8 or 1)2(NHC6H2Cl3-2,4,6)> 13 respectively.Compounds 8 and 13 form stable Lewis acid-base complexes 1)3L> t-4 12> and 1)2(NHC6H2Cl3-2,4,6)L> (L = Et2O 14, py 15 or 3,5-dimethylpyridine 16).The presence of a slow ligand exchange for compounds 9 and 12 was investigated by 1H NMR spectroscopy.The molecular structures of 1, 3, 4, 8 and 12 have been confirmed by X-ray crystallography.
