The reactions of the diaminebis(aryloxido) ligand precursors [Me 2NCH2CH2N(CH2-4-R-C 6H3OH)2] [R = C(CH3) 2CH2C(CH3)3, H2L 1; R = CH3, H2L2] with Mg nBu2, ZnEt2 and AlEt3 create complexes of general formula [M2(μ-L-κ4O,N,N,O) 2] (M = Mg, 1a for L1 and 1b for L2; M = Zn, 2a for L1 and 2b for L2) and [Al2(μ-L- κ3O,N,N,O)2Et2] (3 for L1) in good yields. Compounds 1a-3 were characterized by NMR spectroscopy and ESI-MS experiments. The definitive molecular structure of 1b·CH 2Cl2, 2a·H2O, 2b·CH 2Cl2 and 3 was provided by a single-crystal analysis and revealed their dimeric nature with an M2O2 planar core. The L1 and L2 ligands coordinate as the dianions in a tetradentate/bridging manner in 1b, 2a, 2b and in a tridentate/bridging mode in 3. The NMR spectra showed that the solid state of these compounds is essentially retained in solution. The Royal Society of Chemistry 2013.

Pure amine-bis(phenol) ligands are readily accessible in high yield, often >90%, when the Mannich condensation reactions are performed "on water" or in poly(ethyleneglycol) (PEG). Microwave-assisted synthesis dramatically reduces the time and energy required to prepare these molecules, typically from 24 h to 5 min. The approach seems to be widely applicable (7 amines and 5 phenols were tested to yield a diverse set of bis(phenol) ligands). Significant improvements in yield were observed for ligands derived from di-tert-amyl and di-tert-butyl phenols, possibly resulting from a hydrophobic effect. Single crystal X-ray diffraction data for the ligand derived from p-cresol and N,N-dimethylethylenediamine is reported.
