Synthesis and characterization of cis-dioxomolybdenum(VI) complexes having furil as precursor molecule

Abstract

Synthesis of some new dioxomolybdenum(VI) complexes having general formula [MoO2(mac)](acac)2, (where mac = tetraazamacrocyclic ligands derived from condensation of furil with 1,2-diaminobenzene or 2,3-diaminopyridine and their reaction with β-diketones) using dioxometal ion as kinetic template are reported. The prepared complexes have been characterized by molar conductance, elemental analyses, infrared and electronic data. The spectral data indicate that ligands act as tetradentate chelating agent. Due to their biological relevance, molybdenum catalyzed oxygen transfer reactions have great interest. All the dioxomolybdenum(VI) complexes have octahedral geometry with six coordination.
