  摘要：

  1,1-Diethynyl-1-stannacyclohexane (5) was prepared, and its reaction with triethylborane or 9-isobutyl-9-borabicyclo[3.3.1]nonane gave the corresponding spiro-tin compounds 6 and 7 with a stannole fragment, The molecular structure of the derivative 7 was determined by X-ray analysis (triclinic, space group P (1) over bar; a = 835.2(7), b = 1117.5(2), c = 1165.6(2) pm; alpha = 72.05(3), beta = 74.32(3), gamma = 50.61(3)degrees). Treatment of 6 with trimethyltin ethoxide gave at first quantitatively the spiro-tin compound 8 with a 2-stannolene unit which rearranges upon heating into the spiro-tin compound 9 with a 3-stannolene unit, The reaction of 7 with trimethyltin butoxide gave quantitatively another tetracyclic compound 10, analogous to 8, All compounds were characterised by H-1, B-11, C-13 and Sn-119 NMR data. Numerous coupling signs (n)J((SnH)-Sn-119-H-1) and (n)J((SnC)-Sn-119-C-13) and (2)J((SnSn)-Sn-119-Sn-117) were determined by 2D(13)C/H-1 and Sn-119/H-1 heteronuclear shift correlations. Compound 7 was studied by solid-state C-13 and Sn-119 CPMAS NMR. This revealed the presence of a second crystalline phase in the bulk of the solid material, as confirmed by powder X-ray diffraction data. Sn-119 CPMAS NMR spectra of 7 show resolved scalar Sn-119-B-11 coupling ((3)J((SnB)-Sn-119-B-11) = 68 +/- 5 and 65 +/- 5 Hz).

  one case, using the strongly electrophilic B(C6F5)3, a zwitterionic intermediate was isolated and structurally characterized by X-ray diffraction analysis. The question of reversibility of the 1,1-carboboration is addressed. Multinuclear magnetic resonance spectroscopy (1H, 11B, 13C, 19F, 29Si, 119Sn NMR) was used to characterize the intermediates and the stannoles as the final products. Some of the NMR
