摘要:
A series of zinc and copper complexes supported by 1, 3-diaminobenzene, 1, 2-aminobenzylamine, 1, 3-aminobenzylamine and m-xylylenediamine was synthesized and characterized. Reaction of 1, 3-diaminobenzene, 1, 2-aminobenzylamine, 1, 3-aminobenzylamine and m-xylylenediamine with Zn (OAc)(2)center dot 2H(2)O and Cu(OAc)(2)center dot H2O in alcohol, methanol or tetrahydrofuran resulted in the production of five novel zinc and copper complexes: 2, 4, 6, 8 and 9. Moreover, the structure of each of complex was determined by X-ray diffraction analysis. Every complex was also characterized by elemental analysis, H-1 NMR and IR. The complexes were then used to catalyze the Henry reaction and good catalytic results (65-99%) were achieved. The catalytic activity of the complexes was determined by H NMR. (C) 2010 Elsevier B.V.
