  Reactions of SnMe2-bridged biscyclopentadienes with molybdenum carbonyl to give compounds containing Mo–Sn–Mo units

  摘要：

  In the reactions of double-bridged biscyclopentadienes (EMe2)(SnMe2)(RC5H3)(2) (E = C (1), E = Si (2 or 4), E = Ge (3)), or single-bridged biscyclopentadiene (SnMe2)((BuC5H4)-Bu-t)(2) (5) with Mo(CO)(6) in refluxing xylene, the bridging SnMe2 group migrates from the ligand to the molybdenum atoms to give compounds (6-10) containing the Mo-Sn-Mo units; the bridging group EMe2 (E = C or Si in 1, 2, or 4) does not migrate. It is noteworthy that [(eta(5)-C5H5)Mo(CO)(3)](2)SnMe2 (8) obtained from the reaction of (GeMe2)(SnMe2)(C5H4)(2) (3) with Mo(CO)(6) is a degermylated and SnMe2 group migrated product, another outcome worth mentioning is that the complex 9 is afforded only in the rac-configuration. The stability of complexes (6, 7, and 10) containing the Mo-Sn-Mo unit toward heat and light was also studied. The molecular structures of 6, 9, and 10 were determined by X-ray diffraction.

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

  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.
• Substituted Silastannatetrahydro-<i>s</i>-indacenes as Cyclopentadienyl Transfer Agents in the Synthesis of Silanediyl-Bridged Zirconocene Complexes¹

  The substituted silastannatetrahydro-s-indacenes meso-Me(2)Si(t-BuC(5)H(3))(2)SnMe(2), meso-Me(2)Si(Me(2)C(5)H(2))(2)SnMe(2), and meso-Me(2)Si(Me-i-PrC5H2)(2)SnMe(2), prepared from the corresponding silanediyl-bridged dicyclopentadienide dilithium salts by reaction with Me(2)SnCl(2), were structurally characterized by X-ray diffraction and by H-1-NMR in solution. These cyclic stannanediyl compounds react with ZrCl4 to give selectively the meso diastereomers of the ansa-zirconocene complexes Me(2)Si(3-t-BuC(5)H(3))(2)ZrCl2, Me(2)Si(2,4-Me(2)C(5)H(2))(2)ZrCl2, and Me(2)Si(2-Me-4-i-PrC5H2)(2)ZrCl2, respectively. Reaction of Me(2)Si(2-Me-4-t-BuC(5)H(2)(-) Li+)(2) with Me(2)SnCl(2) gives, instead of Me(2)Si(Me-t-BuC(5)H(2))(2)SnMe(2), the distannyl derivative Me(2)Si(2-Me-4-t-BuC(5)H(2)-1-SnMe(2)Cl)(2). This compound reacts with ZrCl4 to give a 1:1 mixture of the rac and meso isomers of Me(2)Si(2-Me-4-t-BuC(5)H(2))(2)ZrCl2. Ring-opened, racemic distannyl compounds are formed also from meso-Me(2)Si(t-BuC(5)H(3))(2)SnMe(2), meso-Me(2)Si(Me(2)C(5)H(2))(2)SnMe(2), and meso-Me(2)Si(Me-i-PrC5H2)(2)SnMe(2) with excess Me(2)SnCl(2). Competition between Me(2)SnCl(2) and Zr centers for reaction with stannylcyclopentadiene units appears to limit the overall stereoselectivity of the ansa-zirconocene complex formation.
