TEMPLATE SYNTHESIS, CHARACTERIZATION OF HIGHLY UNSYMMETRICAL TETRADENTATE SCHIFF BASE COMPLEXES OF NICKEL (II) AND COPPER (II)
Nickel (II) and copper (II) complexes of highly unsymmetrical tetradentate Schiff base have been synthesized by the template reaction of half-units N-(1-hydroxy-2-acetonaphtone)-1-amino-2-phenyleneimine (HL) and N-(2-hydroxyacetophenone)-1-amino-2-phenyleneimine (HL1) with the glyoxalphenylhydrazone. The complexes have been characterized by elemental analyses, conductance, IR, 1H NMR and UV spe...
متن کاملEnhanced catalyst recovery in an aqueous copper-free Sonogashira cross-coupling reaction.
We report the synthesis of a superparamagnetic nanoparticle MNP (γ-Fe(2)O(3)/polymer) supported dendritic catalyst based on a bulky electron-rich phosphine Pd(II) complex. The high reactivity of this catalyst is described in a copper-free Sonogashira C-C cross-coupling reaction in water, and the significant role of surfactant additives is highlighted in the recovery study.
