Synthesis and Characterisation of 1-[9-(H, Me_3Si, Me_3Ge, ME_3Sn)-9-Fluorenyl]-3,7,10-trimethylgermatranes. The Crystal Structure Analysis of 1-(9-Fluorenyl)-3,7,10-trimethylgermatrane

摘要

The title compounds, viz, C_(13)H_8(R)Ge centre dot (OCHMeCH_2)_3N (1: R = H, 2: R = Me_3Si; 3: R = Me_3Ge) were prepared as mixtures of diastereomers by the reaction of N(CH_2CHMeOSnAlk_3)_3 (7: Alk = Et; 8: Alk = Bu) with C_(13)H_8(R)GeBr_3 (4: R = H, 5: R = Me_3Si; 6 R = Me_3Ge), respectively. The synthesis of C_(13)H_8(Me_3Sn)Ge centre dot (OCHMeCH_2)_3N (13) by the reaction of germatrane (1) with Me_3SnNMe_2 is reported. Identity and structures were established by elemental analyses, ~1H and ~(13)C NMR spectroscopy and mass sepectrometry. The crystal structure of 1 was determined by X-ray diffraction methods.
