Liu, Chao published the artcileSynthesis, crystal structure and catalytic properties of novel Zn-N metal complexes based on ethylenediamine derivatives, Safety of N1,N2-Dibenzylethane-1,2-diamine, the publication is Rengong Jingti Xuebao (2015), 44(1), 287-293, database is CAplus.
Two novel Zn-N metal complexes [Zn(OAc)2L] (L = N,N-dimethylethylenediamine (1), N,N’-dibenzylethylenediamine (2)) were synthesized with N,N-dimethylethylenediamine and N,N’-dibenzylethylenediamine as ligand, and the structures were characterized and analyzed by 1H NMR, IR, elemental anal. and x-ray single crystal diffraction. The catalytic properties of the complexes in Henry reaction of aromatic aldehydes with nitromethane and the influences of the reaction conditions were studied, and the applicable scope of aromatic aldehydes in Henry reaction with complex as catalyst is discussed. The complexes can efficiently catalyze the Henry reaction of different aromatic aldehydes with nitromethane under the conditions as follows: methanol as solvent, complex 1 as catalyst mediated by equimolar triethylamine, and catalyst amount for 25 mol%.
