A trifluoromethyl substituted organoimido derivative of the hexametalate cluster: Synthesis, crystal structure and bioactivity of [Mo6O17(NAr)(2)](2-)(Ar = o-CF3C6H4)

摘要

The hexamolybdate cluster has been functionalized with fluorine-containing aromatic atmine by the DCC (N,N'-dicyclohexylcarbodiimide) dehydrating protocol and a novel bifunctionalized arylimido derivative of hexamolybdate bearing the electron-withdrawing trifluoromethyl group, (Bu4N)z[Mo6O17(NAr)(2)] (Ar = o-CF3C6H4), has been prepared. Complete assignments were achieved for the title compound by elemental analysis, IR, H-1 NMR, UV/visible and single-crystal X-ray diffraction analyses. The preliminary agricultural biological activity test indicated that it has some herbicidal and insecticidal activities. (c) 2005 Elsevier Inc. All rights reserved.
