Synthesis and characterization of heterobimetallic alkoxide triethanolaminate derivatives of zirconium

摘要

Novel heterobimetallic isopropoxide derivatives have been prepared by the 1:2 molar reactions of Zr{(OCH_2CH_2)_2 N(CH_2CH_2OH)}_2 with Al(OPr_i)_3 or Nb(OPr-i)_5 in benzene under refluxing conditions. The reactions of heterobimetallic alkoxide-triethanolaminate derivatives with chelating ligands such as acetylacetone or methoxyethanol have been investigated. All of these derivatives have been characterized by elemental analyses, molecular weight measurements and spectroscopic [IR,NMR (~1H,(27)Al)] studies.
