  Neutron Diffraction Crystallography of meso-R(H)Sb−Sb(H)R and Reactions of R(H)Sb−Sb(H)R and RSbH₂ (R = (Me₃Si)₂CH) Leading to Tungsten Carbonyl Complexes, Methylstibanes, and Antimony Homocycles

  摘要：

  The crystal structure of the meso form of R(H)Sb-Sb(H)R (1; R = (Me3Si)(2)CH) was studied by single-crystal neutron diffraction at 20 K. 1 or RSbH2 (2) reacts with W(CO)(5)THF (THF = tetrahydrofuran) to give meso- and d,l-(OC)(5)W[R(H)Sb-Sb(H)R]W(CO)(5) (3) or R(H)(2)SbW-(CO)(5) (4). Dehydrogenation of 3 or 4 leads to [RSb=SbR]W(CO)(5) (5) or [(OC)(5)W](2)SbR (6). 1 or 2 reacts with MeI and 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) to give R(Me)Sb-Sb-(Me)R (7) or R(Me)SbH (8). 2 reacts with SbCl3 and pyridine to form R4Sb8 (9). Photochemical degradation of 9 gives cyclo-R3Sb3 (10). Dehydrogenation of 1 in the presence of LiAlH4 leads to the cis,trans isomer of R4Sb4 (11), which in the presence of light forms all-trans-11 and 10. Decomposition of 1 in the presence of (BuONa)-Bu-t leads to R6Sb8 (12). The structures of meso-3, d,l-3, 4, 5, 9.2THF, and 12 were determined by X-ray diffraction. The deuterium derivatives of 1, 2, and 8 were synthesized and characterized spectroscopically.

  摘要：

  RSbH2 (1) and R(H)Sb-Sb(H)R (2) (R = (Me3Si)(2)CH) are formed in good yield by reactions of RSbCl2 with LiAlH4. The crystal structure of 2 consists of molecules in the meso form.

  The reaction of RSbCl2 with Li3Sb at -40 degrees C gives the three-membered organoantimony ring cyclo-Sb3R3 (1; R = (Me3Si)(2)CH). In. solution and in the crystal I adopts the structure of a cyclotrialkyltristibane with the substituents in the cis and trans positions.
