Özet
A family of hemi-salen (L1H-L6H) and hemi-salan (L1aH-L2aH) ligands-based N,O-chelated binuclear boron-fluoride [L-n(BF2)(2)] (n = L-1-L-6 or L-1a-L-2a) complexes have been prepared and characterized by a variety of spectroscopic techniques (H-1, C-13 and F-19 NMR, FT-IR, UV-Vis, LC-MS, and fluorescence spectra) and elemental analysis. All of the binuclear boron-fluoride complexes exhibit strong absorption bands due to S-0 -> S-1 transitions and strong fluorescence properties were observed at room temperature in the solution. The binuclear boron complexes containing two naphthyl groups are significantly red-shifted in comparison with the other binuclear boron-fluoride complexes. After the structures are characterized, these hemi-salen and salan ligand-based N, O-chelated binuclear boron-fluoride complexes were utilized to the transfer hydrogenation of the different acetophenone derivatives conversion to 1-phenylethanol derivatives as catalysts.
