  摘要：

  Octamethylbistibole (4a), octamethybibismole (4b), 2,2',5,5'-tetrakis(trimethylsilyl)-3,3',4,4'-tetramethylbibismole (5a), and 2,2',5,5'-tetrakis(trimethylsilyl)3, 3',4,4'-tetramethylbibismole (5b) have been prepared by the reductive coupling of their respective precursor phenyl- or bromopnictoles. The bibismoles are thermochromic, while the bistiboles are not. This is the first observation of differing behavior between analogous distibines and dibismuthines with regard to thermochromicity.

  摘要：

  2,2',5,5'-Tetrakis(trimethylsilyl)-3,3',4,4'-tetramethyl-1,1'-distibaferrocene (2) as been obtained from the reaction of 1-phenyl-2,5-bis(trimethylsilyl)-3,4-dimethylstibole with lithium followed by FeCl2. In a similar manner 2,2',5,5'-tetrakis(trimethylsilyl)-3,3',4,4'-tetramethyl-1,1'-dibismaferrocene (3) was obtained from 1-phenyl-2,5-bis(trimethylsilyl)-3,4-dimethylbismole. Dark red crystals of 2 form in the P1BAR (No. 2) space group with Z = 2, a = 9.243 (2) angstrom, b = 11.310 (2) angstrom, c = 17.345 (3) angstrom, alpha = 76.51 (1)-degrees, beta = 79.23 (2)-degrees, and gamma = 73.18 (1)-degrees. A full structure has been determined and shows a ferrocene-like arrangement in which the trimethylsilyl groups are arranged in a staggered fashion. In solution a barrier to ring rotation for both 2 and 3 of DELTA-G double-ended dagger = 13 kcal/mol can be estimated from variable-temperature H-1-NMR spectroscopy.
