The Crystal Structure of (C6H5)3SiSH and (C6H5)3SiSBr and the Preparation of the Iodosulfane (C6H5)3SiSIThe preparation of the halogenosulfanes Ph3SiSBr and Ph3SiSI from Ph3SiSH and N-halogenosuccinimide is reported. They are characterized by vibrational spectroscopic measurements. Ph3SiSBr crystallizes in space group P1 with a = 899.3(8) pm, b = 941.3(7) pm, c = 1 051.4(7) pm, α = 109.88(5)°, β = 99.23(6)°, γ = 96.78(6)° and Z = 2. Ph3SiSH crystallizes in space group P21/c with a = 1 879.4(8), b = 966.3(5), c = 1 845.2(9), β = 107.84(4), Z = 8. The halogenosulfanes decompose in polar solvents by formation of sulphur and triphenylsilanhalide.
Notes:
Es wird über die Darstellung der Halogensulfane Ph3SiSBr und Ph3SiSI aus Ph3SiSH und N-Halogensuccinimid berichtet. Ihre Charakterisierung erfolgt schwingungsspektroskopisch. Das Ph3SiSBr kristallisiert in der Raumgruppe P1 mit a = 899,3(8) pm, b = 941,3(7) pm, c = 1 051,4(7) pm, α = 109,88(5)°, β = 99,23(6)°, γ = 96,78(6)° und Z = 2, das Ph3SiSH in der Raumgruppe P21/c mit a = 1 879,4(8) b = 966,3(5), c = 1 845,2(9), β = 107,84(4), Z = 8. Die Halogensulfane zerfallen in polaren Lösungsmitteln unter Schwefeleliminierung zu Triphenylsilylhalogeniden.
