In this paper 1 methyl 2 ethyl 3,3 di(3,5 dimethoxyl 4 hydroxyl)benzocyclopropane and 1 methyl 2 ethyl 3,3 di(3,5 dihydroxyl 4 methoxyl)benzocyclopropane were first synthesized.展开更多
Chial Complexes of Mn3+, Fe3+, Ni2+ and Cu2+ were prepared from chiral Schiff Base ligand obtained by condensation of new type methyl 5-(1,1-dimethylethyl)-3-formyl-4-hydroxybenzoate synthesized by this work with (1R,...Chial Complexes of Mn3+, Fe3+, Ni2+ and Cu2+ were prepared from chiral Schiff Base ligand obtained by condensation of new type methyl 5-(1,1-dimethylethyl)-3-formyl-4-hydroxybenzoate synthesized by this work with (1R, 2R)-1,2-diaminocyclohexane. The new chiral ligand and complexes were characterized by elementary analysis, 1H NMR, IR and UV-Vis.展开更多
