  摘要：

  Fourfold hydrostannation of tetravinylsilane affords the first generation metallodendrimer Si(CH2CH2SnPh3)(4) (1). Selective bromination yields Si(CH2CH2SnBr3)(4) (2), which can be reduced by LiAlH4 to give Si(CH2CH2SnH3)(4) (3), containing 12 reactive Sn-H bonds. These novel dendritic organotin compounds were characterized by elemental analysis, spectroscopic studies (H-1-, C-13-, Sn-119-NMR; IR) and by single-crystal X-ray structure determination. The molecular structures of 1 and 3 reveal increased conformational constraint in 1; the average Sn-H bond length in 3 is 1.60(7) Angstrom. (C) 2000 Elsevier Science S.A. All rights reserved.

  hydrogermylation of Si(CHCH2)4 with Ph3GeH yielded Si(CH2CH2GePh3)4 (1). In contrast, Sn(CHCH2)4 and Sn(CH2CHCH2)4 reacted with Ph3GeH under the same conditions, forming Ph3Ge(CH2)2GePh3 (2) and Ph3Ge(CH2)3GePh3 (3), respectively, whereas the reaction of Sn(CH2CH2CHCH2)4 and Ph3GeH afforded the expected tin-based metallodendrimer Sn[(CH2)4GePh3]4 (4).

  A series of novel first-generation silicon-centred tin dendrimers Si(CH2CH2SnR3)(4) [R = CH3 (3), Bu-i (4), C CCH3 (5), C6H4CH3-4 (6), C6H4OCH3-4 (7), (CH2)(4)OCH2CH2OCH3 (8), CH2SiMe3 (9)] was prepared by the reaction of Si(CH2CH2SnBr3)(4) (2) with the appropriate Grignard reagent or LiCH2SiMe3 in tetrahydrofuran. The new compounds were characterized by multinuclear NMR studies (H-1, C-13, Sn-119), mass spectrometry (MALDI-TOF, EI) and elemental analyses. The molecular structure of Si[CH2CH2SnBr3(THF)(2)](2)[CH2CH2SnBr3(THF)](2) (2a) was determined by single-crystal X-ray diffraction. (c) 2006 Elsevier B.V. All rights reserved.
