Streszczenie

The diaminebis(aryloxido) ligand precursors H2L1 and H2L2 [H2L1 = Me2NCH2CH2N(CH2-4-CMe2CH2CMe3-C6H3OH)2; H2L2 = Me2NCH2CH2N(CH2-4-Me-C6H3OH)2] were synthesized by a straightforward single-step Mannich condensation. Their reactions with 2 molar equivalents of MeLi in thf afforded [Li4(μ-L-κ4O,N,N,O)2(thf)2] (1a, L1; 1b, L2) and unexpectedly small amounts (∼9%) of [Li6(μ-L-κ4O,N,N,O)23-Cl)2(thf)4]·thf (2a·thf; L1; 2b·thf, L2). Stoichiometric reactions of LiCl, MeLi and ligand precursors H2L led to the formation of 2a and 2b in high yield (∼80%). All compounds were characterized by chemical and physical techniques including X-ray crystallography for H2L1, H2L2, 1b, 2a and 2b.
