Synthesis and Characterization of Organogallium or Indium Complexes of Aroylhydrazones

Organometallic compounds of Group 13 metals are potential precursors for MOCVD and ceramic materials, important co-catalysts for polymerization of olefins. Five dimethylgallium and two dimethylindium complexes of aroylhydrazones, prepared by condensation of aroylhydrazines with substituted benzaldehydes, have been obtained by the reactions of aroylhydrazones with trimethylgallium or trimethylindium in benzene in nearly quantitative yields. All the compounds obtained have been fully characterized by IR, ¹H NMR, Mass spectroscopy and ele-mental analysis. In the complexes, the metal is directly bonded to the oxygen of the hydrazone group and enaminic nitrogen to form intramolecular coordinated five-member ring structure.
