Deprotonolysis of the N,O-bidentate pyridyl functionalized alkoxy ligands, 1,1-dimethyl-2-(pyridin-2-yl)ethanol ( LH), 1-phenyl-2-(pyridin-2-yl)ethanol ( LH) and 1,1-diphenyl-2-(pyridin-2-yl)ethanol ( LH), with 1 equiv of AlMe gave the corresponding dimeric metal-monoalkyl compounds [ LAlMe] ( 1), [ LAlMe] ( 2), and [ LAlMe] ( 3), respectively. Compounds 1- 3 were characterized by H and C NMR spectroscopy analysis, and the molecular structures of 1 and 2 were further confirmed by X-ray diffraction analysis. In the presence of PrOH, aluminum compounds 1- 2 exhibited excellent catalytic activity for the solvent-free Tishchenko reaction under mild conditions. In addition, the catalyst 3 can be easily isolated and recycled three times without a significant decrease in activity. [ABSTRACT FROM AUTHOR]

In the title compound {systematic name: 4,4'-[1,1'-(hydrazinediyl-idene)bis-(ethan-1-yl-1-yl-idene)]bis-(benzene-1,3-diol)}, C16H16N2O4·2C3H7NO, the (E,E)-2',4'-di-hydroxy-aceto-phenone azine mol-ecule is centrosymmetric, the mid-point of the N-N bond being located on an inversion centre. All the non-H atoms of the azine mol-ecule are approximately coplanar, the maximum deviation being 0.017 (2) Å. An intra-molecular O-H⋯N hydrogen bond occurs between the azine N atom and the hy-droxy group. In the crystal, azine and di-methyl-formamide solvent mol-ecules are linked by O-H⋯O hydrogen bonds.
