  摘要：

  The synthesis of bridged binuclear complexes (Me2E)[(eta(5)-C5H4)M(CO)](2)(mu-CO)(2) [E = Si, M = Ru (3); E = Ge, M = Fe (2), M = Ru (4)] is described. Insertion of SnCl2 into the metal-metal bonds in these complexes affords a type of hetero-nuclear cyclic metallic complexes (Me2E)[(eta(5)-C5H4)M(CO)(2)](2)SnCl2 [E = Si, M = Ru (7); E = Ge, M = Fe (6), M = Ru (8)]. Complex 6 reacts with Grignard reagents RMgX to yield alkyl (or aryl)-substituted analogues (Me2Ge)[(eta(5)-C5H4)Fe(CO)(2)](2)SnR2 [R = Me (9); R = Ph (10)]. AU of the complexes were characterized by IR, H-1 NMR and elementary analysis. Both 6 and 8 are still characterized by Sn-119 NMR. The molecular structure of 6 has been determined by X-ray diffraction. Crystals of 6 are orthorhombic, space group Pcab with a = 13.499(2) Angstrom, b = 16.883(6) Angstrom, c = 18.368(4) Angstrom, V = 4168(3) Angstrom(3), Z = 8, Dx = 2.044 g cm(-3), R (R-w)= 0.044 (0.059).

  Reactions of SnMe₂-Bridged Bis(cyclopentadienes) with Iron Pentacarbonyl: Migration of the SnMe₂ Group

  摘要：

  In reactions of the singly bridged bis(cyclopentadiene) (SnMe2)((BuC5H4)-Bu-i)(2) (1) or the doubly bridged bis(cyclopentadienes) (SiMe2)(SnMe2)(RC5H3)(2) (R = H (2), R = Bu-t (3)) with Fe(CO)(5) in refluxing xylene, the bridging SnMe2 group migrates from the ligand to the iron atoms to give compounds (5, 7, 9a,b) containing the Fe-Sn-Fe units, together with the corresponding destannylated products (6, 8, 10a,b); the bridging SiMe2 group (in 2 and 3) does not migrate. However, in the reaction of the doubly bridged ligand (GeMe2)(SnMe2)(C5H4)(2) (4) with Fe(CO)(5), the SnMe2 group undergoes a similar migration to produce the complex GeMe2[(eta(5)-C5H4)Fe(CO)(2)](2)SnMe2 (12), containing the Fe-Sn-Fe unit, both SnMe2 and GeMe2 groups migrate from the ligand to the iron atoms to yield the product [(GeMe2)(eta(5)-C5H4)Fe(CO)(2)][(SnMe2)(eta(5)-C5H4)Fe(CO)(2)] (11), containing one Fe-Ge bond and one Fe-Sn bond, or the SnMe2 group is cleaved to afford the destannylation product GeMe2[(eta(5)-C5H4)Fe(CO)](2)(mu-CO)(2) (13). The stability of complexes 5, 7, and 12 containing the Fe-Sn-Fe unit toward heat and light was also studied. The molecular structures of 9a,b, 11, and 12 were determined by X-ray diffraction.

  A series of doubly bridged bis(cyclopentadienyl) tetracarbonyl diiron complexes (7–13) have been synthesized by the reaction of the corresponding ligand (1–6) with Fe(CO)5 in refluxing xylene. It is unusual that the reaction of ligand (GeMe2)(GeMe2)(C5H4)2 (3) with Fe(CO)5 gave the complex (GeMe2)[(η5-C5H4)Fe(CO)]2(μ-CO)2 (10) as the main product which lost the GeMe2, only a small amount of the expected
