  Bimetallic complexes with ruthenium and tantalocene moieties: Synthesis and use in a catalytic cyclopropanation reaction

  摘要：

  The reaction of the tantalocene dichloride monophosphines (1-2) with the binuclear complex [(p-cymene)RuCl2](2) gives the heterobimetallic compounds (p-cymene)[(eta(5)-C5H5)(mu-eta(5):eta(1)-C5H4(CH2)(2)PR2)TaCl2]RuCl2 (3-4). The air oxidation of these bimetallic species 3-4, leads to the cationic hydroxo tantalum ruthenium derivatives 5-6. The last ones are easily deprotonated by a base to afford the oxo analogues 7-8. A preliminary assessment in catalytic cyclopropanation of styrene with tantalum ruthenium bimetallic complexes 3-8 as precatalysts revealed a cooperative effect with a subtle role of the early metal fragment.
